CAUDICIFORMS AND OTHER SUCCULENTS


Welcome in my caudiciform and succulent world !

It was made to give you some education, some useful help and some fun
from succulent surroundings.

An each grower will be able to find something for yourself here.

A beginner: " I have bought a plant and I do not know how to take care of it..."
- Do not worry, neither do I.

An advanced: " What about testing soil acidity ? "
- I wonder the best way would be eat it...

A professional: " Go to hell with your taxonomical views ! "
-OK, before it we should strike off 80% synonyms in bidding catalogues !

What are they ?

Succulents:
Succulent plants are all plants with some special physiological equipment
which give them capability to survive dry period in arid areas they usually live.
The basic signs are ability to retention of water in cells and CAM metabolism.
Of course, there are many other plants adapted to survive in arid climates, but they
cannot be said succulents. We formally designed them as xerophytes -
some of them with C4 metabolism.
We have to admit, there are many differences because the nature is a great composer
and it is simply difficult to say everything is clear and strict according to our botanical specifications.
(Caraluma frerei has CAM metabolism in a stem and together C3 way in its leaves !!!)

Caudiciforms:
There are many plants belong to succulents or xerophytes with thick roots, bulbs, or chunky stems.
Ordinarily we state two groups of them - caudiciforms with caulorrhiza - thick basic of bodies
or pachycauls - plants with massive stems. Among this definition there are lot of differences too.

And it all includes many genera and families
Let's look at some of them

Plants from my collection and short talking about them:

Protože sem chodí i návštěvníci z jiných zemí, bude postupně celá tato sekce přeložena do AJ. Našinec s tím problém mít nebude, kdežto pro cizince je čestina velmi obtížně pochopitelná. Vybral jsem tuto sekci proto, protože pěstitelů sukulentů je myslím více než kaktusů a když sem příjde někdo odjinud aby si tady mohl i něco přečíst.

 

 

Fittonia cv. mini - an amazing plantlet but not for everyone

You can buy this bright pink veined-leaved cultivar in a lot of supermarkets. It is not a typical succulent as we know them, but I must put it here because of its beauty. But there are some difficulties with cultivation too.

Firstly, you need to know that the plant - as all plants from supermarkets - is potted in a transportation substrate only !!! You will be forced to repot it but not immediately after buying. After you obtain the plant, let it become aclimatized for a month or two. Then you can repot it.

Secondly, it needs a lot of light, but not too much of the direct sun, still (after buying, of course too) regular watering, but not overwatering, with high humidity. Substrate should be dark rich humus plus peat, as we usually use for tropical plants. During winter keep the same conditions as in summer.

Last but not least, you must pay attention to overdrying - if it happens, do not put the plant in a bin, give it a lot of water and lying leaves will erect back in four hours. It means the small Fittonia needs a permanent supervision...so I cannot recommend it for beginners, rather for "upper-intermediate" growers, tough it costs 2 Euros only...

 


 

Sinningia speciosa cv. - a plant we cannot overlook in any collection

Where to find a caudex which should not has only a nice tuber and leaves, but also flowers and could have be cultivated in the apartment ? This idea fully meets Sinningias cultivars. We could grow it outdoors under a roof in hanging pots in a place where the direct sun cannot, or rather indoors at the window. Sinningia cultivars want enough light, but only scattered. I recommend to start with buying free tubers from the beginning of April, instead of buying plants pre-grown in a poor soil in holland pots. First, they are cheaper and we can also choose only the quality and substantially sprouted. Tubers have upper roots growing underneath from the top, so be careful when planting tubers, they must be about 1 cm below the ground. With water, we start in the spring with caution untill it comes clearly to the full growth leaves, what usually takes the whole April. Then again watch out for overdrying. Watering during the flowering has to be substantial, but should avoid overwatering and misting leaves. Manuring during the vegetation is desirable. In practice, multiply by tissue culture, seedings are challenging. Old and properly cultivated tubers usually remontant and so each one may also produce over 50 flowers per a season, so we can enjoy them for a month at all the time. The flowers from the second batch are little bit minor. After foliage drop in the fall put the tubers in a cold dry room as cacti. Lack of light does not matter.

How to Calibanus hookeri ?

There aren’t any difficulties with cultivation Calibanus hookeri, a special plant among plants, if we realize some basic rules. During its youth we should pay attention on overwatering because it could get a plant putrefaction. A frequent mistake is in a substrate, it is the best we put it in a heavy clay with lots of stones, quartz sand and a crystalic limestone, crushed shale or a marlite. We can add a little bit of granulate fertilizer. A suitable place would be on direct sun, in an outdoor culture could be as well, but with covering against heavy rains. It prefers warm. In the nature a caudex can rich 2 meters and get over 1000 years !

Watering must be infrequent and irregular, but flood, really a lahar. If its bulb is fitting only about 1cm under surface of the substrate, then the plant grows quickly. For Calibanus truly the better grows the less we intervene it. In this case we use an adequate pot so as not to be forced replant it often.

On the 19th November, 2009 – there was 19 degrees C. above zero here ( usually is winter ), so I decided to replant my Calib but I was amazed with amount of roots. That is what we say - right moment !

 

I generally describe these plants like a soil-glutton, but where did the all soil come ?
As a spice note I would like to tell that the roots grew up from almost nothing during 11 months…Then remember a good substrate make a good success !

 

Cussonia paniculata  Ecklon et Zeyher 1837 

Cussonia paniculata is an interesting plant with a huge pachycaul base and big leaves. Cultivation is quite an easy, similar to Calibanus cultivation. Heavy soil with some minerals, lots of sun and water during grow period ( from April to December ). Keep it in the greenhouse or a flat or under the sky, with temperature about +20C. During winter about +10C with no water, then leaves will fall down. If you have a warm place rather to +20C you must give it some water during winter period as well. This rule refers to youth (up to 3 years old) seedlings much more. Older plants we can keep during winter with no leaves in full dry period. It is an ideal species for balcony and outdoor seasonal cultivating.

There are many synonyms of this plant on the market, but it is only one botanical variable species indeed. So be careful to prevent from somebody wants you serve a trick.

A traditional snap from repotting. A bulb has 4x8 cm dimension. It was 6 years old, and the bulb was all under the substrate. Now it grows quickly.

 

Zantedeschia cv.  

Callas (Zantedeschia) – how to them ?

These tuber plants have been importing in our countries recently. But breeder’s experience and some information about them - there is still too little, in that reason, because one author copy something from another one and you can find websites with the same nonsense. Something you search on Wiki but we are asking: “How to them ? “

Buying: If you buy the tubers from stores you have to pay attention on their quality. At first check out each bulb, but it is not easy, because they are wrapped in non-transparent plastic bags so we cannot look at them properly. Therefore we examine them by palpation if they do not have a lot of defects, spots, fungus, decays and even they are activated as well. With good thick and not much long sprouts.

Do not forget ask a bidder about guaranties, it depends on each store and the tubers are not cheap.

Placement: Keeping it strictly in a garden is not only a way. Bad weather could damage stems and flowers with wind, heavy rain or thunderstorms. I consider the best place for Callas is to put them in a cover balcony, a greenhouse, a winter garden connected by house or simply pitch them under the window in a bright room.

Planting: A pot must be really large and deep to hold the tubers comfortably with enough space for a lot of next roots. I used nr.28 for three small tubers and nr.35 cm “bucket” for three tubers 10cm in a diameter. Substrate must be prepared carefully with a tropical nutritious soil, some peat and a good drainage. Put that in the pot to its bigger half, fit tubers evenly, and cover with another soil almost to the top.

Activation and growing: Planted pots give into a warm place and as the spring comes start with watering after one – two weeks dry period. When the first leaves appear the substrate must not dry up. For a next development is necessary warm, humidity, sufficiency of light, and leaves misting.

Flowering: Only mature tubers make a flower. Lateral ones we use for another reproduction. The flower can persist during a month or even more. I have a sort where the flowers had stayed on all season long till leaves died and they still were there…

Termination of the season: In our country during August or late the leaves sink down as we finish watering before it. Then we take the tubers in and put them into a total dry place with low temperature about +10 C. for their hibernation. At the end of the winter we replant them in to a new fresh soil and wait for the approaching spring.

 

Picture: Here are some Callas tubers, quality on the first sight.

 

A root activity of tubers after the first watering.

 

Picture: Sort “Mango” with flower 10 x 15cm, it was more than I had expected…

 

Conclusion: I hope I have brought some clarification in issues of growing Callas. There are many sorts on the market, with almost all colours of flowers you can imagine yourself, so do not hesitate if you grow on some of them.




Zingiber officinale  Roscoe - Well, I have bought it and so what  

There is no doubt a ginger is a caudiciform plant. I have bought it only for an experiment, but it cannot grow in our country. It needs only a greenhouse here in Central Europe, in spite of this, results cannot be guaranteed too. It is better to buy and eat it simply…This subtropical plant is one of the most medicinal- herb in the whole world. Besides garlic…

 

The hidden testicler  -  Seyrigia humbertii  Monique Keraudren 1960

Cucurbitaceae is a family with a large diversity of species. One interesting group shows semi-bushes or small trees Seyrigia from Madagascar. Seyrigias are not many famous in our cultivation. Most known of them is Seyrigia humbertii (in the picture). It makes small tubers on its roots look like testicles. They work as storage of water during dry periods. Slim hirsute stems protect themselves from hot and bright sun. A flower is bland and a fruit is tiny oblong pumpkin. The plant is easy to cultivate. Keep it in heavy clay with some sand and let it in warm place with bright light. We do watering during the spring and the autumn with dry periods between it. Watch out for over drying in greenhouses. We can arrange these plants in hanging pots or in bonsai bowls. If you put their testicle potatoes above the surface it can look attractive, but it can damage all plant, because they are adapted to live under substrate, so remember this.

 

Stephania suberosa Lewis L. Forman 1980 

These plants are difficult to cultivate and not to mention the propagation by seeds…
Nobody had told me there had not been allowed water them more often that one month so I annihilated all of my plants and now do not want to see these species at all. So listen to my advice: It would be better to buy bigger plants instead of smaller ones. Substrate – I am not much sure about it, but in botanic gardens, they are planted in normal tropical soil with lot of peat. Watering after foliage gets to full size only one month from April to May! Protect them from brown decay, using stimulator and some chemicals. Do not use fertilizer, even some phosphoric ones! Keep plants in warm and bright place not on the direct sun. If you are not sure with water, do only misting instead. Still in warm place 25 C above. I will keep my fingers crossed for you…

 

A cock in a flowerpot !

Once a day I was selling some plants in the market with my colleague. And finally there was left only a piece that nobody wanted. So I had taken it in my home and it was standing at my window for many years. At first it was such a small penis, but during the times it has grown up to 5 centimetres in a diameter and still has penis proportions, but huge… If the plant has something like tits I would be pleased, but what the hell is always wrong with this?!

We cannot defend against common currency: Who was born as a cock – stay as cock all his life long…                                             

a new photo is on the way...

 

Pseudobombax ellipticum

It is a nice tree with a thick trunk, beautiful leaves and gorgeous flowers. We usually cultivate it like a bonsai tree. The clue to success is in a good suitable substrate, but I still have not discovered that .As an each subtropical plant needs warm and light. A replanting taken often is not useful. During the season we can give it a lot of water with some fertilizing. Try to hold the plant in active growth as long as you can in the late autumn. Cutting could help with growing fat base, but think it over properly.

a new foto is on the way...

 

Sinningia  leucotricha

It is also known under an ugly name Rechstaineria. This plant is an amazing, and more years it has, then more turns in prettiness. The bulb can reach 30 cm in diameter, and incoming leaves after winter are really silver with bunch of nice flowers. Put the plants in some clay with some soil, sand and peat, and cultivate it like cactuses. Do not overwater and do not mist them. Older pieces keep dry with reluctant periodic watering. This plant must be in every succulent collection!

 

Monadenium rubellum

It is the best to cultivate this taxon in full clay and lots of sand under the direct sun. We need prevent from overwatering, because the plant is easy to get some putrefaction. And a bulb can be destroyed by that at once. If it happens, we need not to be sad. All its branches we can bring to root again in clear sand with some powder stimulator. The taking root is an extremely easy, because plant propagates itself by them, besides the seeds of course.
In the picture there is three months old branch rooted after former bulb had died.

 

Mirabilis jalapa  Hook. 1844 

Mirabilis jalapa does not belong to common succulents and it gets best in outdoor culture. But why couldn’t be some caudiciform plant in a balcony? The tubers look really ugly…

...but thereafter they flower with these nice flowers during all the summer and the autumn, so why not? Do not forget replant them into a fresh soil every year.

 

Galinsoga parviflora Cav.

There was one interest story about the plant Mirabilis jalapa and that was “a parasite". I bet before that without help you would hardly looking for any pest in a below snap.

 

Middle plantation Mirabilis jalapa there was grown weed plant Galinsoga parviflora syn. Galinsoga quinquiradiata Ruiz et Pav., Wiborgia acmella Roth, Wiborgia parviflora (Cav.) Kunth in the family Asteraceae, in Czech otherwise known as Pěťour maloúborný (try to say it in a correct way ). This persistent weed had adjusted its mimicry that completely merged with Mirabilis plants. And it had done so perfectly that it was discovered by accident. It is a very dangerous plant in agricultural practice and that needs to exterminate with all means. It was introduced to us from the high mountains of South America. In the collections wouldn’t be obviously tolerated at all, but you can see that it cannot be seen!



Plectranthus ernstii, Leslie Edward Wastel Codd.

The plant was named in honour of its discoverer, Ernst van Jaarsveld, who found it on the coast of the province of Natal in South Africa in1982. There is a one in the picture, 8 years old (in 2007) and provides an excellent material for some experiments... Caudex is branched in more shoots and it has 8 cm x 5 cm wide base, now slowly fills the area pot No. 10. This is an absolutely amazing plant and cultivation is quite an easy, it only does not like the direct sun.

 

 

Petopentia natalensis (Schlechter) Bullock 1954 

This is a popular plant from the family Asclepiadaceae. Unfortunately, as all members of the family it suffers from pests, felt scales or eriococcids and very from red spiders. Therefore, it is necessary spraying leaves during vegetation to maintain the leaf material. Because this is the most important factor in annual increments of caudex and its loss would be the worst thing that can happen to us. Watering should be impact and heavy for larger plants, for smaller ones regularly in small doses. I use a heavy substrate with 30% gravel. Pictured is a two-year old caudex thick 4 cm

 

Gasteria prolifera  Lem. 

This succulent has every right to be written about him on the front pages, since nearly 90% growers led to growing succulent plants. Instead, it ends in bins, if was banished from the all collections of long ago altogether. It is difficult to enumerate the number of plants among non- succulents growers, in apartments, offices, corridors, where serve as one of the toughest house-plants at all. Deposed plant with multiple other types of succulents in pots always looks handsome. Apart from permanent overflowing, frost and darkness can withstand everything. Now is included in the family Asphodeloideae. For medicinal juices it is sometimes used in a medical practice. As time it overgrows slightly, but that's just the right moment to donate offshoots. Let us not forget about our old friends.

 

 

Gasteria pillansi var. ernesti - ruschii f. variegata  (unknown) . 

You are looking at a real miniature large only 2cm, where 1 mm branches are capable to root. A plantlet is an attractive, easy to grow, and every branch and leaf is differently coloured. In the Namib desert there exists in the adjacent areas of different numbers of similar gasterias now arranged in clusters around the G. bicolor, but this plant is not in the picture. The entire circuit would have deserved a thorough taxonomic evaluation, which can only be helped by field survey. Yellow in the collection is impressive and there has already bred a number of more or less of successful hybrids.

 

Delosperma cooperi  L. Bolus 

As a man passes one collection of succulents (exactly mine) finds out that the caudiciforms are soon about nothing. It is one beautifully hideous potato as the second, clouds of foliage and that is so all. Occasionally something rots to say that. This boredom of potatoes can refresh a beautiful succulent rock plant native to South Africa, Lesotho - Delosperma cooperi. It grows easily from seed, placement can take in the sun and grows like the lush green lawn, actually it's a surface-covering plant with that you can hide many ugly corners of the retaining wall, etc. A sunlit and drained habitat is required. Plant is not winter-resistant. Therefore it is necessary to secure enough of their own seeds, because in our conditions, it’s easily converted to an annual plant. Top cuttings of non-flowering shoots easily take root and hibernate in a bright greenhouse at about +15 C. Overflowing never likes. Flowers are truly fabulous.


 

Aloe variegata, is it self-fertile ?

Aloe variegata, is it self-fertile?
So it bloomed myself this well-known nice aloe. An inflorescence formation started after a few sunny days in March. I have only one adult plant, so I was not interested in pollination. The course of flowering was dismissed much faster than with relatives Gasteria, even though individual flowers were more about 1x6cm. Later, I was surprised with making several fruits (1x2cm) on fading flower-stem that I did not remove in order to the plant could stretch a nutrients to its body back from it. Careful inspection showed that at the time anywhere near flowered no haworcie or something with which could easily lead to interbreeding. Problems auto-fertile plant species is not sufficiently explored, I have myself fought with it eg. in the genus Gymnocalicium for many years. When the fruits ripen, I'll see what has been done, or to try to planting. And so the question of whether Aloe variegata is self-fertile can say that - I do not know.


 
 
Now I can say that it is not !

 

Dorstenia foetida 

Pleasant miniatures, which save you a lot of water to grow and pests do not suffer them at all. (Maximum I saw springtails, but will not hurt, just pure seeds). The photo on the right there is Dorstenia foetida sp. Mecca, Lavranos 20546, that is quite different from the type, especially lower and chunky caudex, coarser and more silvery bark and oval leaves. Description varieties would be appropriate, however, to take account of the variability in plant locations, it is at the discretion of those experts... D. foetida is multiplying easily from selfs-seedlings that are most often held in neighboring pots where mature seeds are impacted. Collected and planted seeds near their parent plants germinate very well too, whereas a normal seeding is usually worth the old cable only. It is best to know this for E. leuconeura. It is beyond the scope of modern science to explain why this is so. Maybe it depends on the natural position of the seed on the substrate, where the fall is rotated to the correct position - sprout pole underneath, or rather on bioneuronic field around adult plants, on the chemistry of the soil around them ... Anyway Dorstenia succulents species are very nice plants in collections.


 

 


EUPHORBIA SUCCULENTS

 

Euphorbia ambovombensis  Rauh et Razafindratsira 1987 

Here is another miniature, which cannot be missed with specialists in Madagascar spurges. Plants bloom at an early age and stem has diameter up to 1 cm. It later based a small caudex beneath it while the plant develops additional terminals. Cultivation is the same as with E. decaryi. The photo shows naked little caudex forming below the substrate. Do not pull out it necessary, its development would be slowed. Show the caudex after the times when it will be worth it.

 

What is Euphorbia avasmontana, polyacantha and comp.?

It is not my habit to give here some unknown bush, but at the first I couldn't help myself. According to collector deposits and descriptions of the authors E. avasmontana occurs in Southern Namibia, and extends into Northwestern Africa, and it has dark green stems, newly budding thorns have a red color. I turn it seems to me that E. avasmontana occurs in the basin of the river Avash in Ethiopia, from where the first plants were imported to Europe and accordingly were also described. The stems have brown or black skin, gray with black spined ends during sprouting white with darker tip. Today this plant circulates under other names. Well, in the picture there is a species that has its stems light green and budding thorns as well. I got no plant locations (what it was about as useless), I like much, but the name ... that would finally rather polyacantha ?

Note: So as not to be there enough misunderstanding I have bought another plant looks like E. avasmontana – with dark green stems and red thorns, but it has a tag E. virosa. These plants are basically situated in Orange river area, Southern Angola, Namibia etc. Therefore I have decided to put all havoc in order, now it is easy:

Euphorbia polyacantha Boiss., 1860, Cent. Euphorb. 1860, 25. - light green constricted body, grey spines

Euphorbia virosa ssp. virosa Carl Ludwig von Wildenow 1799, Sp.Pl., ed.4 (Wildenow) 2(2): 882. 1799 [Dec 1799] – rather dark green longed body, red spines


It may include another synonyms :

Euphorbia dinteri A. Berger 1906, Monatsschr. Kakteenk. 1906, 16: 109

Euphorbia avasmontana Dinter 1928, In: Repert. Spec. Nov. regni. Veg. Beih. 1928, 2:96

Euphorbia kalaharica Marloth 1930, S. African J. Sci. 1930, xxvii. 338, 340.

Euphorbia karasmontana and Euphorbia coerulescens are invalid not registered name.

Conclusion: It might be only one species dispersed in large area, almost 3/4 arid areas in Africa, many islands and even in Southern Europe. So I tend to think the best name is Euphorbia virosa ssp. virosa

So here they are:

Euphorbia polyacantha, Boiss.

 

Euphorbia virosa, Wild.

 

Euphorbia decaryi var. spirosticha Rauh at Buchloh 1987

Slow growing decorative miniatures. Older plants are slowly changing into a hill with side branches and terminals, and a massive caudex swollen below. For the cultivation standing there is suitable a lot of heat, no direct sun but enough light, nutritious sandy substrate, regular watering with small doses of water. It can be multiplied by 4 ways: sowing, layering offshoots, rooting leaves and tissue cultures ... :-)

 

Euphorbia enopla Boissier 1860 

This wonderfully spined plant should not be missing in any collection of euphorbias. E. enopla belong to 19 families of the section in conjunction with E. aggregata, anoplia, ferox, fimbriata, heptagona, mammillaris, pentagona, polygona, etc. E. enopla inhabits large areas in Southern and Southwestern Africa. This plant is very similar to E. ferox, differs from it, however, leaner body and structure flower, but the huge variability of both species caused that is difficult to decide where E. enopla ends and where it begins as E. ferox. To make the matters worse, this is again very similar to E. pulvinata, which also creates multiheaded clumps, sometimes even about 50 000 heads. It is also on many sites and again very variable and so the taxonomists have a lot to do... These plants will delight us growers with its geometrical beauty and ease of growing.

 

Euphorbia fimbriata  Scopoli 1788 var. variegata

A variety of a famous spurge with high aesthetic value, unfortunately, there is not much in vogue among growers. When grown in the classical container it grows quickly, lies down, uproots, so it must be bound to a support. This plant looks much better in a hanging round pot, where individual stems put up over the edge in all directions and grow pipe way. Whole package reminds a real head of Medusa, although this kind has nothing in common with types of "medusae". But it even so soon will occupy the large space, especially when growing in a greenhouse. To not change it in so many cursed euphorbias sticks, there is necessary to plant it into a mineral substrate and watering with modestly dosed. At worst can help section.

There is clearly visible each of the different additions on the plant according to phenophases- it is not a growing defect, according to them - we can calculate the age of each shoots!

 
 
 

Euphorbia gymnocalycioides Gilbert et Carter 1984

A great type from area in Eastern Sidamo in Ethiopia, which was named by virtually identical appearance with thorn less variety of species G. quehlianum that grows just on the opposite side of the Earth. Botany teaches us that a convergence is caused by a similar development in a similar environment. But the crop is not identical, you cannot afford do with that spurge what with ordinary gymnos. Plants are sensitive to the watering during dark and cloudy March days when waking up too growth. Much better is be patient and wait until May. Here again it is not very suitable to follow soaked in direct sunburn on such plants obtain decay immediately, and particularly in the case of small seedlings. This will avoid initially with clayey substrate and disciplined grower. Adult plants bloom profusely, and last no more, so can grow in nutrient garden substrate at neutral Ph. Sand is never enough. Plants suitable everywhere where there is enough of scattered light, balanced temperature, wintering is necessary completely dry. The housing culture not take up much space, the seeds are very small. The main growing period is spring and then a bit in the fall.

 

 

Euphorbia horrida Boissier 1862

Quite variable species with many variations, the plant in the picture might rather be called ssp. minor, but I'll see what else grow out of it. Otherwise it is spurge already completely domesticated in our collections, so there aren't growing problems.

 

Euphorbia ingens (Meyer) Boissier 1862

In fact, it's going on the E. ingens, although today are circulating many different treelikes Euphorbia under that name. It also was most referred to as E. abyssinica although it has a lighter epidermis with radial curved stalks away from the areola, so it looks a bit like a washboard and differs even at inflorescence. Worse is to discern it among them ... I would like at this point to remember E. candelabrum, but more and more I think that perhaps does not even exist. E. ingens has a darker stem with yellow drawing or without, from the beginning usually grows straight up the top about two meters up and then make branches, but it is not a condition. At the time of vegetation have the tops several rows of narrowly plantain leaves that fall off soon. These plants are suitable to collections only in youth, then it is necessary to cut and take root just especially nice branches...

It is a totally huge and can rich 20 meters height.

 

Euphorbia candelabrum Kotschy

According to the above mentioned I add an image of plant commonly cited as E. candelabrum. It's something between E. trigona and E. ingens, but with a rather specific growth when individual stolons sat parallel from each other at least and grow candlestick = candelabra manner, and generally it creates thin tree at an organ pipe shape, not unlike a large genus of broom cacti species Browningia etc. E. candelabrum is distributed after throughout the whole Africa, particularly in the east. I believe that under this name circulates more species (poorly designed) that they deserve detailed taxonomic evaluation.

 

Euphorbia leuconeura Boissier 1862

This is a very popular plant propagated not any different way than from self-seedlings. I could add here advice on how this can be improved yet, but owing to the enormous flood of seedlings, I am not interested in to be stoned... A placement can significantly change the shape of the plants: under the sun there will grow spindly and pale yellow stalks barely two centimeters thick with little foliage and the appearance of "branched palm tree", but more in the shade and enough bottom heat plant is a low, green stems have at least 4 cm in diameter with abundant giant leaves ... I somehow keep the first version with minimal watering and forced dropping leaves several times a season. There is also a variety with bright red leaves in autumn, only a classic one gets yellow. Even so, unfortunately, it becomes the "weeds" of our collections.

 

Euphorbia mammillaris L., var. minima  

This is a new form of a beautiful well-known succulent. Again from the Holland plantations, who could resist? Unfortunately, this once let go forget about taste - all plants have a bacterial scarlet fever and many other diseases, you will throw it complete as I did. I have failed to save even one branch and it's enough saying to me ... All the plants are nourished by stimulators and sprayed with a retardant and a treetop molding liquid. It is nestled in the stinking transport peat, an ideal combination for ejection. Who manage healthy offshoots in heavy clay, let me know.

 

Euphorbia meloformis ssp. valida (N. E. Brown) G.D. Rowley 1998 

Here is another common type of spurge. This species takes quite a lot of space: 10 cm diameter of body with a 20 cm inflorescence of stems and thorns over it.

 

There is a sowing from the same plant. When the seedlings get a little sunburn they decorate with beautiful red striations.

 

Euphorbia milii var. milii Des Moul. 

The Crown of Thorns, Christ Plant or Siamse Lucky Plant was the oldest and first euphorbia imported to Europe at all. The plant in the picture is from a specimen that is in our culture more than 100 years. Because this kind was took by gardeners, now there are countless cultivars. The description says that an apical inflorescence is androgynous, one female flower is on a long stem and male in five on the bunches, what is nonsense, because here it is completely vice versa. Like other spurges contains milky latex, that is not only toxic, but caustic and carcinogenic as well.

 

Euphorbia piscidermis M. G. Gilbert 1973 

Purchased plants and they immediately begin to bloom in January. Grafted plants have a problem lies in the fact that after some time their base pushed against what caused over branching or crestate. Basically, the plant is partly destroyed. So making seeds on these plants may suffer, however offshoots are also suitable for further propagation. As soon as I obtain any, I will try to root them...

 

Euphorbia pulvinata Marloth 1909

The species mentioned above, which grows on a large area in South Africa and elsewhere. In old age it creates multiheaded colony of thousands of headers. The number of individuals in that pillow several meters in diameter is not limited and can accrete ad libitum. And it propagates both ways of offshoots, as well as from their own seeds by self-seedlings. A large clump of plants is a defence against temperature fluctuations and pests. Even survive fires. The only pest that could destroy the plant is, as usually - human. With growing there aren't any problems. Nice and easy type to collections. Limitation of watering is not at the expense of appearance - the plant is compact, rounder and additions are not so wild. The substrate can be any. A very variable species is very similar to E. aggregata, E. ferox, etc.

 

Euphorbia stellata Willdenow 1799 

These coloured "snakes" crawling on all sides. Free culture plant apparently beneficial. Let it grow like this for some time and then see what caudex has been done at the bottom.


 

So I just did not resist, and 3-year old seedlings pulled from the pots in the year 2009. If nothing then at least I have to commend the substrate that I had developed for Euphorbia has proved excellent. That's the pot with a diameter of 8 cm and it was not easy to put the plants out is more than obvious, everyone had underground caudex size 3 x 20cm (running into roots). Horror, what will happen next?


 

Haworthia coarctata var. coarctata Haw.

At the plant of this section Hexangularis I am not able to assess whether the name Haworthia reinwardtii authorized other species, or just a synonym for this plant, I am inclined to the second option. In the terminology between coarctata / reinwardtii there is chaos, not just in terms of variability. It should be clarified which form comes from what site, but in many other transitional forms, the overall clarity picture somehow get losing. Unless there H. reinwardtii exists at all. The plant is of course a fantastic kind in the collection, nicest of all (especially ssp. “zebrina” and company). Growing is a medium difficult and plants require shade, mineral, nutrient substrate and regular but careful watering. A disadvantage is in the relatively slow growth, only larger clumps grow faster.

 

 

Haworthia coarctata var. coarctata fma. chalwinii Haw.

From well-known locations Vanwyksvlei, from all fairly clearly distinguishable form with tiny stems and leaves. Otherwise, for the cultivation pays what for typus, but it is necessary to add more sun and heat. Plants hate permanent overwatering substrate and easily get rotting. Growth is even slower that at previous one, but it's a beautiful plant to a collection.

 

Haworthia cooperi (Baker) var. pilifera ISI 1762

Detail of optic windows that are nothing more than natural fibre optic cables. But here we again lag behind Nature, because within these skylights there are other ramifications, which filter sunlight and distribute it into the photosynthetic tissues... This beautiful Haworthia is easy and lasts grow in any soil mixed with sand. Plant has no specific requirements for placement.

 

Haworthia cymbiformis var. cymbiformis (Haw.) Duval 

It is From Thornkloof, Cape, South Africa. This is a type of sympathetic Haworthia also a very variable species. Image shows the plant at overwintering. Pests do not suffer these plants, that would have to be right, Haworthias - as well as most members of the family Asphodelaceae sucking and piercing insects do not eat. If so - then that's enough to shot the grower... With this Haworthia we can make an interesting experiment: We put in the outdoor culture in the summer ... where it turns to an Ariocarpus!

Just for the order, I add that family Asphodelaceae (Aloacae) includes the following genera:

Aloe, Asphodeline, Asphodelus, Astroloba, Bulbine, Bulbinella, Bulbinopsis, Chamaealoe, Chortolirion, Eremurus, Gasteria, Guillauminia, Haworthia, Hemiphylacus, Herpolirion, Jodrellia, Kniphofia, Lemeea, Lomatophyllum,  Paradisea, Poellnitzia, Simethis, Trachyandra.

Plants are well grown in them, they look attractive, are quite hardy and resist pest suffering. Completion of one of the larger families would be certainly a meritorious scientific work.

 

Kalanchoe blossfeldiana Poelln, cv. Calandiva  

Plants from this genus are my favourite. I have a few “stuffed animals”, other bare ones pretty bloom again. In 2010, flooded the markets this hot novelty cultivar, I am looking for a pink form, because the flowers are really fabulous and long lasting. The plant requires common nutrient substrate for normal house plants, just a little more permeable. Placement can be with not much sun, only about 4 hours a day. Misting is recommended, but not into the flower. Spraying with Arpalite against thrips and red spider is desirable. Let it work 15 minutes and then shower that (non-flowering plants). Regular cutting and fertilization is a prerequisite for further rich flowering.

 

Kalanchoe dinklagei

After a hard cutting it turns in a nice bonsai. This is a typical example of nanization sheets in response to the cutting, what is typical for most of Kalanchoe. Regular moulding can produce a nice tree crown and a leaf can be reduced to 1/10 the original size. Increments are slower, plant requires heat otherwise there aren't any growing problems.

 

Kalanchoe orygalis

A pleasant plant that is cultivated as species described above and it reacts on cutting in the same way. Nanization can reduce the leaf more noticeable, I estimate that up to 1/20 the original size. The location can be moderately bright, with watering regular, but modest, in order to maintain the shape. Multiply by sheets or branches, a substrate with a share of any sand, just succulent ideal for novice growers.

 

Kalanchoe hildebrandtii

This is another stuffed toy with unpleasant root activity. We can use it as a good material for a root-bonsai.

 

A thief in the collection

Not only steal and parasite people, but also this happens in the wild when the competition is huge, or conditions miserable ... and see my collection.... There are pictured aerial roots of Kalanchoe hildebrandtii that stretched and bored into the pot of Kalanchoe dinklagei. Aye well then it would grow. But K. hildebrandtii broke the records. I did not see it in time, the both plants were in the corner, and the whole pot was grown through with roots of parasite that was stealing water and nutrients from your neighbour there...

And how it stuck there...

 

Echinocystis lobata - Cucurbitaceae

A balsam apple, a wild cucumber or a prickly cucumber. ( CZ - Štětinatec laločnatý ). Why do I give it here actually? This plant has been starting with massive spread along lowland type of rivers lately and people ask what it is. Damn gardeners! I do not know who has dragged it here, but this monotypic plant was originally in good faith begun to grow in gardens for drying decorations and as a climber plant. Climber that is, the vines can grow lengths up to 150 m for one summer and can topple the whole plot, also neighbours will it love ... In our nature (Central Europe) it becomes another disaster for our nature, next to the Impatiens glandulifera, Heracleum mantegazzianum, Reynoutria spp. How much more it will be? And cucumber it certainly is not, especially fruits and seeds caused poisoning with hallucinogenic effects. There is a speculation that it goes on lysergic acid derivative, what would it set the government (and growerment too !!!) in a nice panic, because the plant grows almost over the whole Earth :-) There is pictured a ripe and an unripe fruit of prickly cucumber.

 

Anacampseros rufescens

It's a nice little succulent with beautiful flowers. Even so, it does not require heat as regular sunlight - enough light - not heat stroke. The figure shows that its fruits and seeds are very interesting too. Just try to do sowing...

 

Nananthus vittatus (N.E.Brown) Schwantes

This is an absolute amazing plantlet. This is the way how I imagine a succulent bonsai myself.
For a few first years keep it under substrate to obtain massive roots. After the times we can put out the roots above the surface and prepare it as a root-bonsai miniature with big bright flowers! The plant needs a mineral substrate, lot of direct sun, not much water during two periods in the season = only in spring and in autumn. Protect it from pests and scale insects. Species has many synonyms, be careful when you will buy. Propagation can be managed by seeds or branches.

 

Crassula falcata H. Wendl.

Here is another brilliant succulent. It has interest body and can surprise us with gorgeous flowers ordered in a cymes. A main stem splits after each flowering and multiplies by 2 for next season. Before all plant will be exhausted and fallen down, we can root some offshoots, or leaves to have ready a new fresh plant. Propagation by seeds is possibly, but we need to have two genetic different species to get seeds successfully. We do the seedling immediately after we obtain them. Plant requires a lot of sun, periodic water, a good mineral substrate and regular fertilizing.

Návštěvy sbírek:

Sukulenty IVO ŽÍDEK:

Na návštěvy sbírek chodím nejraději sám. Může se to zdát divné, ale myslím si, že než se prohánět s upoceným zájezdem od pultu k pultu, je daleko lepší si takto na to najít více času. Ty rostliny si to totiž zaslouží. Člověk si takhle více všimne, pěstitel má na něj taky čas, tu se zastavíme a povykládáme nad obzvlášť vyvedeným kaudexem, či nějakou novinkou, nebo probereme téma substrátů atd. To organizovaná skupina tyhle možnosti nemá, proto jsem ještě využil pěkného pozdního podzimu a na hodinku zaskočil do sbírky Ivo Žídka ve Staříči:

Adenia glauca pomalu přechází do klidového stadia

 

Adenia spinosa oproti tomu pokračuje ve vegetaci ačkoliv je již půle listopadu

 

Adenia spinosa ani na starších rostlinách není znatelné nějaké zbrždění růstu 

 

Adenium - i když již nekvetou je na tuto kolekci příjemný pohled

 

Adenium -detail, aneb krása kaudexů

 

Adenium obesum -import z pěstíren 15cm kaudex a hned u vstupu do skleníku na čestné stráži skoro dvoumetrová Cyphostemma laza.

Aloe longistyla si ještě kvete v takhle pozdním a abnormálně teplém podzimu

 

Anacampseros alstonii s kaudexem 10cm. Komu se líbí kratší název, ať si to vede jako Avonia tak jak ji přeřadil Rowley v r. 1994

 

Cyphostemma juttae s pěkně vytvarovaným kulatým kaudexem a typickou papírovou kůrkou

 

Chcete -li někomu něco slíbit "najisto", řekněte: ...až pokvete Euphorbia abdelkuri !

 

Euphorbia aeruginosa se vyskytuje v mnoha variacích a barvách, tady je obzvlášť vyvedená forma

 

Euphorbia bupleurifolia se již nezalévá a přechází do klidového stadia pro bezpečné zimování

 

Euphorbia gymnocalycioides 6-8 cm velká, na jedné rostlině s punčoškou na lapání semen. Ani ne za pět minut už byla punčoška na zemi a semena vysypána kdesi v kaluži vody na podlaze skleníku...

 

Euphorbia horrida v.striata je dnes již považována za běžný druh, ale mně se líbí.

 

Euphorbia iharanae  u specialisty na Madagaskar nesmí chybět 

 

Euphorbia sepulta je již vzácnějším druhem a vyplatí se roubovat 

 

No a tady jméno zatím nebude, protože rostlina z okruhu E. milloti teprve čeká na svůj popis

A zde je již úplná superspecialita, nový nádherný nález, rovněž zatím bez popisu

 

Euphorbia suzannae už v našich sbírkách zdomácněla 

 

Euphorbia tortirama pěstována přírodním způsobem ("ať to roste jak chce"), zde mně ruce svrběly vytáhnout ji z květináče a podívat se co se udělalo dole... 

 

Euphorbia turbiniformis je stále ještě raritou a proto se roubuje.

 

Operculicarya decaryi zde je pěkně napěstovaná starší rostlina

 

Operculicarya hyphaenoides je jediná v ČR a právě se na ni díváte. 

 

Pachypodium bispinosum "vypasené" tak, že se nevejde do květináče...

 


Pseudolithos eylensis řádně napěstovaný už i s odnožemi...

 

Pyrenacantha malvifolia spravená po havárii. Byla zakoupena s polouhnitým kaudexem (taky bych mohl vyprávět), zkušený pěstitel však špatnou tkáň vyřezal, kaudex umístil s ránou nad substrát aby se mohl vytvořit kalus a rostlina byla zachráněna a pomalu si formuje normální podobu. 

 

Uncarina roeoesliana i v podzimu se na sukulentech dá nalézt leccos pěkného - v tomto případě plody na unkarině. Ano opět mi bylo potvrzeno, že tyhle kytky v našich podmínkách neformují tolik žádaný kulovitý kaudex, ale spíš jen válec. Kdy už to někdo zkusí ve volné kultuře ? Asi se toho budu muset ujmout sám...ale žádný špás to nebude.

 

Zygosicyos tripartitus jsem zastihnul už v bezlistém stavu o to ovšem víc vynikne 20cm dokonale napěstovaný kaudex.

 

Ani skalní kaktusáři neodejdou bez potěchy - je zde dost pěkných kaktů k vidění a momentálně se zde dává dohromady i rod Discocactus. 

Závěr:  hovíte-li sukulentům (obzvlášť z Madagaskaru) a máte-li cestu na Severní Moravu neopomeňte navštívit tuhle sbírku.

  


 

BZ TEPLICE:

Botanická zahrada v Teplicích je jednou z významných zahrad u nás. Obsahuje velice slušný materiál, kvalitně zkomponované skleníky a příjemné exteriéry. Šíře botanického záběru jednotlivých expozicí je značná. Mně přirozeně zajímala sukulentní flóra, ale musím poznamenat, že tropický skleník je opravdu skvostný, nelze ani opominout horský tropický skleník, expozici uhlítvorných rostlin - zkamenělin i jejich živých reliktů a příbuzných, dále velmi pěknou venkovní zahradu, kde si na své příjdou jak milovníci dřevin tak i skalničkáři.

A toto již je vstup do xerického skleníku:

Kmen Kalanchoe beharensis ! 

Kalanchoe beharensis

Šedivější jinak vykrajovaný list a robustnější vzrůst má Kalanchoe decaryi. Jmenovku jsem  sice nikde neviděl , ale troufám si tvrdit, že to je ono.

Hned u vchodu upoutá poměrně robustní Glottiphyllum regium

Pedilanthus tithymaloides, známý jako ďáblová páteř (Euphorbiaceae)

Květenství s květy a plody u Jatropha podagrica (Euphorbiaceae)

Euphorbia intisy je zajímavý strom...

Xerosycios danguyi zde roste skoro plevelným způsobem (Cucurbitaceae)

U této mammilárky byl název druhu "angelensis", což je zřejmě paskvil, protože jde zjevně o komplex centricirrha. Mně však zaujala pěkná pěnovitá mostróza, kterou nakypěla jedna hlava. Kdyby se to naroubovalo, zas by byla jedna raritka na světě...

Kvetoucí Cycas sp. protože na jmenovku jsem nedokouknul a šlapat po kytkách se mi nechtělo.

Tady je všechno jasné:

 

Bezmála půlmetrový kaudex známé sloní nohy...chtěl bych vědět kolik toto váží...

Okolo 25 cm velký "nechutný" kaudex stefanie, hned bych ho bral...

Uncarina peltata tu má prostor a dobré podmínky

Takřka převrácená část kmene masivní Cyphostemma juttae

Cyphostemma juttae plodí a prosperuje dobře i když druhá polovina rostliny byla odřezána (asi  zavázela do uličky)

A tohleto je unikát, kvůli kterému jsem přišel. Teprve v roce 1997 popsaná Xanthosoma robustum (Araceae-Arónovité) Lokalita na štítku mezi Siuna a Rosita, Nikaragua. Nalezena byla též i na ostrovech v Havajském soustroví. Rostlina ve skleníku je asi metr vysoká, kmen je u báze tlustý cca 15 cm a pozvolna se kónicky zůžuje směrem k vrcholu. Nepatří mezi sukulenty, protože nemá CAM metabolismus, ale přesto mezi všemi kaudexy a pachykauly ohromí. Pravděpodobně bude silně toxická, moc údajů na toto téma zatím není k dispozici. Exemplář je umístěn v tropickém skleníku, čili pochází z humidních oblastí.

 

 

Pachira quinata a Chorisia speciosa -srovnání kmenů

 

Phytolacca diocia známé jako "opilé dřevo"  - "palo borracho" a hned vedle detail další ohromující kytky -Podražce obrovského Aristolochia gigantea, ať už se specializujete na jakékoliv rostliny, pod touhle liánou musí každý milovník rostlin stát v úžasu.

 

 Závěr:  jedna návštěva opravdu nestačí...
