These succulents are long-time favourites in Australia especially for covering up embankments where it's difficult to get other things to grow and even harder to mow!
here are a few in our garden from last October,

Cohan, there are more differences between those 3 species than meet the eye from those photos... don't have time to post photos now, but D. congestum has orangey winter colour, D. nubigenum turns red, and D. basuticum stays green. There are also subtle foliage differences. I got the pink ones from Beaver Creek.
D. cooperi is shown as having the same hardiness rating as D. congestum on a site I was looking at last night... hard to make any sense of such ratings, except by trying the plants in one's own conditions.
Delospermas in cultivation are more likely to have the wrong name on the label than the right one.
D. congestum is one of the abused names, usually applied to small mat-forming plants with yellow flowers. D. congestum as originally described is an upright shrublet with white flowers and is not known in cultivation.
D. nubigenum is a mat-forming species with yellow flowers, often sold as D. congestum or with a cultivar name like 'Gold Nugget'. Sometimes it has a white eye and it is likely that these plants have a hybrid origin. There is also now a 'White Nugget', again an unknown hybrid. There is no other Delosperma that you'd mistake for it, smooth rounded yellow-green leaves forming a mat no more than an inch high.
This same plant is also sold as D. basuticum, again a completely different species. The name D. basuticum is also applied to a similar mat-forming plant with yellow flowers, but having sharper leaves minutely toothed along the edges. I'm pretty sure this is also incorrect since D. basuticum is described as a having pink flowers.
D. nubigenum is extremely cold hardy and very tolerant of moisture. Mine survive the weather but not the slugs!
Very interesting about the species confusion, Iann.
Bolus' original description of D. congestum (in latin) is shown in the attached link within a discussion about the frequently-confused species; the flowers are white, turning lemon-yellow ("alba, marcescentia citrina") as they persist:
http://www.fgas-sukkulenten.de/downloads/delosperma_e.htm
I couldn't find Bolus' description of D. nubigenum but here's an extremely terse description of it from the South African National Biodiversity Institute (SANBI) - it does note pink petals. (The other specimen described under the same species heading was not in flower but the leaves are said to match Bolus' description.)

(Amazing what one can find on the internet! :))
lori and simon had both mentioned they were trying Aloinopsis (spathulata?) at the end of last winter, i dont recall whether we ever got an update?
did they survive last winter?

Sorry, I didn't see this question until now. No, my A. spathulata didn't survive outdoors (the fleshy leaves were all dessicated, I think, and broken off), but if I have seeds left over, I'll try it again. (There may have been one random factor that contributed to their demise... the outdoor Xmas tree stand may have been set on them, which certainly would not have helped!)
Wow, that was clunky! I couldn't find that reference to a D. nubigenum with pink petals at SANBI and I don't think its possible to link directly into particular search results. Possibly it was referring to the specimen as being unusual. I'm sure a D. nubigenum with pink flowers would be a big hit in cultivation. In any case, D. nubigenum is well documented with yellow flowers: "c. 30 bright yellow longer petals, c. 20 shorter ones, c. 10 deep yellow threadlike filamentous staminodes, around the c. 70 stamens". Good flowering seems to depend on getting a good flush of early spring growth which is difficult in the UK. I speculate that too much water early in the year may also suppress the flowers.Confer
The name D. congestum is used extensively but is clearly wrong and clearly documented as wrong. The original type is not known and the latin description has caused confusion, but clearly it never referred to D. nubigenum. It may not refer to anything, many of the early descriptions were made from dessicated dead specimens, although Bolus tended to have better material.
Other yellow Delospermas common in cultivation, and there aren't very many, are D. echinatum and D. rogersii, both distinctive and hairy, and D. crassum which is a fairly standard sub-shrub Delosperma. There is an unnamed tufted species from Lesotho which has almost inevitably been sold as D. congestum. I show one in my garden, clearly different from any named species. It is very hardy but the thickened rootstock seems a little sensitive to winter wet. Anything else with yellow flowers is likely D. nubigenum or some hybrid of it.
It might be interesting to compare two images published in the thread, namely
thanks for the details (some repeated, i know)repetitio mater studiorum if I remember
i have seen 'sani pass' offerings, not sure if they are the same one or not...A compact bright-purple-flowered species is offered as 'Sani Pass' too.
waiting to see if the two 'gold nugget' types i have have survived the winter-still in pots, sunk after an early cold blast (around -20) in oct; when the snow receded recently, they seemed to still be alive, with most of last season's foliage dead, but they still have to get through the rest of the spring freeze/thaw..Our climate is certainly milder, -18 C in January. Unprotected plants in the experimental rock garden in a local nursery
nubigena, latin noun, formed from clouds. Used both for mound (=cloud) forming plants and in this case for plants growing in the cloud layer. It is masculine!Yes, it is. Substantiva in apposition retain their own gender.
Species epithet nubigenum is common, and nubigenus is also found.Errors are common. Epithets ending in -colum, -colus, -fugum, -fugus, -genum, -genus
Here's a new species, or possibly a newly discovered old species, that I'm hoping will take to the garden because it has some of the nicest flowers on a Delosperma. Its lovely in a pot but already has a taproot a foot long and wants to expand more. Delosperma deilanthoides (possibly = D. galpinii).Delosperma galpinii occurs in Natal at 2000m.
Delosperma deilanthoides is still alive in the garden. -15C this winter although this one is close to the house so probably didn't get that cold. Like most Delospermas it grows better in a pot than in my limestone soil.Fantastic. You should disseminate the seeds. I ask whether the shoots remain alive trough winter.
On a different note, these things startled me this week.But it should be a winter grower. Logically, it cannot be under totally dry conditions in winter. I cannot imagine its watering in the garden.
First is Neohenricia sibbettii. This is a very hardy little thing and a piece that I tested in the garden survived this winter. Pick a dry spot though! Nocturnal and highly scented.
It's not a winter grower. Not in habitat and certainly not in England. You can give some winter water if it is warm and sunny, but I'd suggest not if it is frozen. Obviously it gets some moisture out in my garden all year round, but plants under cover are quite happy to sit out the winter dry.So it can be a quite interesting enrichment in the garden. Interestingly, it originally flowered in March in Kirstenbosch, not in spring or summer as Delosperma. I suppose the plants cultivated by you flower in autumn too.
Habitat is on the edge of the central plateau. Cold dry winters, hot dry-ish summers but nights usually still cool. Rainfall erratic.Clear.
I don't have anything that could possibly be Gold Nugget, but I do have this other yellow flowering tufted species from Lesotho which has a single flush of flowers in spring. This is sometimes sold as D. congestum, although it isn't that species.iann,
The flowers are a fairly standard five-locular design. You can see them better in this closeup. The capsules are somewhat strange, almost as if they tried to double up the locules and very nearly made it.Yes. Locules are divided by false septa. A comparison with a Stomatium fruit might be interesting.
Stomatium capsule. I believe these are false septa forming chambers at the bottom of the capsule that retain some seeds for longer. Sometimes they are not always obvious (second picture), but can be scraped out to leave a fairly standard five-locular capsule (third picture).Thank you. In my opinion, the placenta is not so elevated that it could be called a false septum.
Hi,Try to understand what was written previously in the thread. Delosperma basuticum and Delosperma congestum are two completely different species, neither yellow-flowered. The plant you cultivate is neither Delosperma basuticum, nor Delosperma congestum, but a scientifically non-described species. There exist several introductions of the species, 5 different of known origin in my possession. The variants undoubtedly represent one species. It has little sense to distinguish the variants because of crossing. Furthermore, Delosperma nubigena, not Delosperma nubigenum, is the trailing yellow-flowered fertile plant, the common sterile variant of which is sometimes called Delosperma deschampsii Hort. Whether the latter is a cultivar of Delosperma nubigena or a hybrid of it is in stars. Delosperma lineare is a white-flowered upright plant seldom in cultivation. The names are applied arbitrarily and casually to Delosperma species in horticulture.
Here's a pic of my Delosperma Congestum. But I would like to know what are the differences between D Congestum & D Basuticum. They seem very close for my non specialist eyes. As for D Nubigenum & D Lineare: are they two
J-P
different species?
Very showy! I could hazard a guess what one of the parents might be, and I have an idea what the other might be too. I guess all will be revealed in due course :)
I'm pretty sure I've never seen either D. congestum or D. basuticum. I don't think anyone anywhere has D. congestum, just somebody decided to slap the name on this plant. Wasn't it Kelaidis and then the name stuck even when he said it wasn't D. congestum at all?Correct about Delosperma congestum but not so certain about Delosperma basuticum. All miniature pink-purple flowered introductions are candidates.
I dislike hybrids, perhaps it is not one.It has classic mesemb pink/yellow cross flowers. It is a hybrid, whether natural or cultivated I don't know.
Sold as 'Gold Nugget', but is not, if I understood correctly.It is certainly the species to which 'Gold Nugget' belongs. It is not clear whether 'Gold Nugget'

I wonder whether anybody has genuine Delosperma sutherlandii which hibernates without shoots.Hmmmm..... well, I don't, I fear.
Thanks Ian for the identification!I don't remember seeing that, and I can't find it now. Shame since these are some of the best Delosperma flowers. Mine are still flowering now, which is quite late. Spring came early this year and summer still hasn't quite arrived.
Have you noticed, that I have already posted a picture of a flowering D. deilanthoides from your seed!
I am very happy with them!
A few mesembs in flower. Delosperma sp Lesotho did its main flush in the early spring heatwave but is actually flowering again. The Titanopsis is a hybrid between T. schwantesii and T. hugo-schlechteri.
Whereas in yellow-flowered nuggetoid Delosperma the 5 or 6 nectaries are broadly separated
(http://www.srgc.org.uk/smf/index.php?action=dlattach;topic=3795.0;attach=298418;image)
in 'White Nugget' the nectaries are almost connate and often forming a lophomorphic ring
(http://www.srgc.org.uk/smf/index.php?action=dlattach;topic=3795.0;attach=298420;image)
Receptaculum structure is apparently different too. Therefore I suggest the hybrid origin of
'White Nugget' one parent being not a Delosperma.
First attempt at growing plants of this genus this spring. So far, so good! ;DThey don't really like dry sunny places. They are mostly alpines ;D That's why they are so hardy. In well-drained soil in summer, you can pour on as much water as you like. In fact in the south of France they will probably grow best in spring rather than the hottest part of summer, and may really fatten up in autumn. In winter they will be most cold hardy when dry, but will survive in well drained soil with rain or snow. Don't be tempted to water in winter even though they sometimes look quite bedraggled. A reasonably sunny spot is important because the flowers only open with sun and because they will become impossibly straggly in the shade.
But I know about nothing about them...except that they like dry and sunny places.
Should I add some grit between the soil and the leaves?
Could you tell me a little more about these two? (Maybe I didn't start with the easiest ones, considering my zone...)
The tiny pink flowers belong to D. 'Beaufort West', and the one flowerless, but with larger "leaves", is D. 'Red Mountain'...
Thanks in advance for your tips!
Delosperma 'Red Mountain' is a cultivar of D. dyeri. I think it is actually a hybrid, because the species has regular pink flowers and this cultivar has flowers that are a classic hybrid colour.However, Dyer wrote in his letter 18 November 1926
I'm late to this thread but must go through and read it in detail. Thought I'd jump in and show a couple photos of a new Delosperma species... it has a tentative name, but until it is published and introduced I'll just call it Delosperma sp. Panayoti Kelaidis gave me permission to post a couple of his photos, so here they are (you may need sunglasses ;D). I'm trialing the plant here in northern New England, can't wait to see some of those brilliant silky flowers.McMark,
http://www.plantzafrica.com/plantcd/plimagescd/delospermdyerlax.jpgBut I can see also in this pretty nice thread, that this splendid natural hybrid is in my own universe rather sure one of the parents of the here shown marvelous colored D. dyeri that kindly was shown some pages before (pls. see next mistreated quote). One strain of the natural D. dyeri hybrid comes in my virtual universe therefore from this real splendid crassuloid hybrid from Tarkastad.

I have had masses of flowers, and it looks like plenty of capsules forming. My experience is that the seed won't germinate until next spring, but fingers crossed I'll squeeze out some flowers next summer.
Chris,
I'm not sure whether you've seen these hybrids, originally from Gordon Rowley. There are three different clones, all crosses between D. kofleri and D. nubigenum. The photos are closeups of small plants, but they are very hardy, very floriforous, and now filling large pots. One is shown next to D. nubigenum.
Ah, thank you, Josef.... we Scots get everywhere, it seems.

D. brunnthaleri hort. ex Eret ex MatkChris,
Here is a photo of the receptacle from D. brunnthaleri hort. ex Eret ex Matk (2009)It is not.
(http://img254.imageshack.us/img254/6416/dbrunnthalerirezeptakul.th.jpg) (http://imageshack.us/photo/my-images/254/dbrunnthalerirezeptakul.jpg/)
The central yellow zone of flowers within some Delosperma species, for. ex. your/Marek's D. aff. hirtum or D. dyeri var. laxum, is rather due to an external pigment coating effekt of pollen.The centre of aff. hirtum is pea green if observed in indirect light and luminous yellow if observed in direct sunshine.
This can be received from very heavy dew or water-supply during opening times of the flower.
The identification of a white flowered Delosperma from northern Lesotho and Natal under D. hirtum is relating to Elsa Pooley in Mountain Flowers - A Field Guide to the Flora of the Drakensberg and Lesotho (2003: 72-73) and based on the unpublished description of D. hirtum var. niveum by Mary Gwendoline O'Connor-Fenton (née Lavis) - see also BOL131458;; BOL131459; BOL131460; BOL131461; BOL131462 and BOL131463 (with a ;D on a certain Facebook entry). Both Ladies were erroneously identifying this species under D. hirtum, but representing rather a southern white flowered variety of D. carolinense N.E. Brown.aff. hirtum is not the white-flowered plant in the pictures presented above. The leaves are considerably different, linear and greyish.
Hermann Jacobsen also published a photo (taken by K. Josefský) of the white flowered variety of D. carolinense erroneously twice under D. brunnthaleri (Jacobsen: Die Sukkulenten 1933: 112 & Handbuch der sukkulenten Pflanzen III 1955: 1307).Thrice, in Sukkulentenlexikon is the image reprinted too.
Very comfortable and almost academic argumentation, Josef. ;) ;DHere is a photo of the receptacle from D. brunnthaleri hort. ex Eret ex Matk (2009)

It is not.
The centre of aff. hirtum is pea green if observed in indirect light and luminous yellow if observed in direct sunshine.A young flower still keeping all its pollen is rather translucent pea-green centered, as soon as the pollen ripe for takeoff and humidity high enough it is rather yellow, whether observed in indirect light or in direct sunshine.
It may really be coloured by pollen dye but in ashtonii and deleeuwiae the pollen doesn't influence centre colour.Great to see that you already found almost also one next level attribute for further delimitation within Delosperma § Eximia. 8)
aff. hirtum is not the white-flowered plant in the pictures presented above. The leaves are considerably different, linear and greyish.Yes, indeed. And already very obvious viewable. But now you know already one very probable ancestor of your shown aff. hirtum, performing here likely suspected the main influence in the flower.

Great to hear that the F1 generation is already homogenous, but this is still not a sufficient evidence for not being a hybrid - here you need to check up also the F2 generation for being homogenous or not.
I suggest you should become more familiar with the work of Gregor Johann Mendel [1822-1884], today referred to as the laws of Mendelian inheritance, especially with the 2nd rule ("Spaltungsregel").

Dyer in 1926 (D. alpina & D. dyeri) contained as well a 3rd species, also described under Delosperma and enabling the necessary singularity for a very probable rediscovery of this until today unkown old Dyer location...Delosperma alpinum, 357 Cata Ridge Dec 1925, 378 Kat Berg near The Gorge Jan 1926, 673 Hogsback Dec 1926
i just got my Pantone color chart out to check on Cohan's marvellously descriptive apricoty/bronzey delospermas. No sign of them.....but they sound so much nicer than Pantone solid to process coated P501 C. ;)
And D. congestum for comparison.If you followed the previous discussion, you would be informed that it is not D. congestum.
Well it is still listed as an accepted name in The Plant List and as a gardener, not a Botanist or a nurseryman I will have to go by that until it is Unaccepted and removed to another place.First.
What you understand under winter hardy? I do not think the plant is winter hardy really.
But the principle itself must test each.

Are there no slugs or snails in Norway?Such nice plants in a summerhouse garden!
I have to grow D.deschampsii in a pot on a windowsill with slugpellets all around it if I want to see a flower.In the rockgarden it was so badly damaged that it was going to be eaten completely if I left it there.Or may be your sp are not so attractive?

I have to grow D.deschampsii in a potBut which species you call Delosperma deschampsii.
Is D. deschampsii an invalid name?It is commonly used yet.Please tell us more.It is unknown to me and to the science probably too.
Great Moravian gave the answer on page 7 in 2010:D.'deschampsii' is the sterile form of D. nubigena.You are right. I first encountered an image of the standard sterile nubigena denoted
My plant is indeed sterile.
The identification of a white flowered Delosperma from northern Lesotho and Natal under D. hirtum is relating to Elsa Pooley in Mountain Flowers - A Field Guide to the Flora of the Drakensberg and Lesotho (2003: 72-73) and based on the unpublished description of D. hirtum var. niveum by Mary Gwendoline O'Connor-Fenton (née Lavis) - see also BOL131458;; BOL131459; BOL131460; BOL131461; BOL131462 and BOL131463 (with a ;D on a certain Facebook entry). Both Ladies were erroneously identifying this species under D. hirtum, but representing rather a southern white flowered variety of D. carolinense N.E. Brown.Christoph,
Hermann Jacobsen also published a photo (taken by K. Josefský) of the white flowered variety of D. carolinense erroneously twice under D. brunnthaleri (Jacobsen: Die Sukkulenten 1933: 112 & Handbuch der sukkulenten Pflanzen III 1955: 1307).
Josef, is the foliage of "Hogan" always so dark- it seems to e a dark purple/red?Maggi, not always. It was photographed in the autumn and was nearly black.
Ich lach michI laugh too. But I justly.
About the man : Sean Hogan of Oregon, in the USThank you, Maggi. It is really interesting and topical, namely at least for me.

The first snowfall of the season has driven me to my computer: I have been intrigued to look over all the postings since I last got on last spring...it has been a very busy year in Colorado and I am in the frenzy of getting seed prepared for exchanges and getting my gardens ready for winter. Mark McDonough let you all get a glimpse of a plant we will be releasing this coming year through the Plant Select program: There are two cultivars of this taxon.Mark and Panayoti, I wonder whether the plants are true seeding, i.e. purple centres, yellow-orange-red tips of flowers, or segregate to pinkish-purplish flowers as, allegedly Delosperma dyeri, 'Red Mountain' does.
The first two pictures are of the selection FIRESPINNER which will be released: it is the redder of two clones. The last picture is of the more orange clone, which has not been released, but which is charming in its own right.
Thought the SRGC forum ought to know about what is promising to be a truly spectacular plant. Blooms of Bressingham is working on the European rights for this.
It has been a spectacular and very hardy and vigorous garden plant for me.
I was rather expecting a show more like this!So you should move to Denver.
johnw - expecting 27c today
In all honesty I am not keen on the colour combination of this one.But my plant is certainly closer to the wild thing
johnw - expecting 27c today

I see there's a Delosperma called D. seanii-hoganii after the great plantsman Sean Hogan out in Portland. Why on earth such a Latin name? Even sean-hoganii or seanhoganii which would have been less ridiculous than that, why not the logical D. hoganii of which Sean might(?) approve. Next will it be Narcissus ianii-bulbii-despotii-youngii?It might be ridiculous for an English speaker but not for me speaking an inflected language.
Peter,A rather poor pic of Delosperma cooperi 'Ruby', but an interesting range of seedlings has started to flower,
your Delosperma hybrids remind me of a few we bought on our visit to see Paul T in Canberra;
They are all called Delosperma cooperi
with gemstone names for the diffeent colours:
Moonstone, Garnet and Ruby!
There was also another one which was called Drosanthemum speciosum Kliprand

They are, though it might be the light.I have a friend who would call that "knicker pink" !

Probably wouldn't make an impression over here .... Steven Hammer's fairly new book, The Titanopsis Group is excellent. http://www.littlesphaeroid.com/ (http://www.littlesphaeroid.com/)
Aside from Hammer's witty prose, which I can read for pleasure, it features some of the most stunningly beautiful plant photographs I've ever seen.
So beautifully grown at such a high latitude Steve.

Johan - Wonderful Delosperma there and so early!
johnw
Pleiospilos nelii.
or - a neat representation of a volcanic eruption! ;)
Always something astonishing in the world of succulent plants.
A few Delo flowers on some cuttings struck in late autumn.
D. basuticum - the name is tentative but certainly the only one that can take anything, anywhere in Nova Scotia.

Maggi,
There exists a place called Aberdeen Road in Eastern Cape
http://travelingluck.com/Africa/South+Africa/Eastern+Cape/_1023789_Aberdeen+Road.html (http://travelingluck.com/Africa/South+Africa/Eastern+Cape/_1023789_Aberdeen+Road.html)
I can find the record for Delosperma aberdeenense (L.Bolus) L.Bolus from Kew , which tells me that this is "the accepted name of a species in the genus Delosperma (family Aizoaceae).
The record derives from WCSP (in review) (data supplied on 2012-03-23) which reports it as an accepted name with original publication details: Notes Mesembryanthemum 1: 135 1928."
I asked before - in 2011- where the "Aberdeen" part comes from - http://www.srgc.net/forum/index.php?topic=3795.msg207706#msg207706 (http://www.srgc.net/forum/index.php?topic=3795.msg207706#msg207706) - and Josef helpfully replied that :
Fermi - You forgot to attach the pictureWhoops! :-[ Pic now added to original post!

Last year we planted a river of Delosperma cooperi, which made a stunning display.Gordon,
Thanks John - he'll know!
I've been trying to identify this little mesemb - the only one I've seen growing around here. This is a long shot - and it, probably, isn't even a Delosperma species! Could anyone help with an id - no matter how tentative?
A thought just occurred to me - maybe a Trichodiadema sp. (looking at the leaf tips...)?
I'm almost tempted to try one or two John. A super carpet of a lovely bricky colour. :)
But was it fog or smoke from the fire?
Hallo Josef,
Hammer hat bereits 2015 das Delosperma sphalmanthoides in Daggodora sphalmanthoides S.A.Hammer gen. nov. umgruppiert.

Also ist das hier geschriebene ungültig.

Why are you writing these things here? This belongs to an international specialist journal. Not in a forum.
Please stop writing such no accepted things here.
fostering excellent science generally involves community engagement rather than regulationThe concept of an authority ordering binding scientific results is shocking.
The concept of an authority ordering binding scientific results is shocking.Science depends on agreed definitions or standards. This proposal to standardise taxonomy (original publication here (https://www.nature.com/news/taxonomy-anarchy-hampers-conservation-1.22064), probably behind a paywall :() is surely only part of ongoing efforts to improve clarity. Like all science and scientific conventions, its conclusions would remain contingent on new evidence, so really I don't see the problem :-\.
Plant taxonomy is a science generated in brains of different individuals.
This proposal to standardise taxonomy (original publication here (https://www.nature.com/news/taxonomy-anarchy-hampers-conservation-1.22064)This is precisely the idea replied and refused in the reaction by IAPT. The article is rather stupid.
