delosperma & aizoaceae

[Great Moravian]

The following image by Chris Schröder depicts Delosperma congestum quite probably.

In contrast, the following image by John and Hilary Birks doesn't depict
Delosperma congestum as claimed but it may perhaps be Delosperma basuticum.

The strange winter checked the hardiness of mesembs cultivated outdoors without protection.
The winners are Delosperma 'Gold Nugget', 'White Nugget', two new introductions
'Diamantové doly 3000' and 'Oxbow 3000' as expected.
Surprisingly, a Stomatium species is as hardy as the previous. It should be one of the
two high altitude species Stomatium geoffreyi and Stomatium gerstneri
despite its identification as Stomatium mustellinum.
Delosperma  'Hogan' survived in a sheltered place, killed in another.
Delosperma 'Beaufort West', 'Graaff Reinet', are killed, 'Safari' nearly killed.

you can enjoy an article on Delosperma deleeuwiae
which is not the misnamed narrow-leaved plant cultivated usually.
The originals of images of putative Delosperma deleeuwiae are at

and

In my guess, the cultivated Delosperma 'Menoaneng Pass'
http://files.zahradnictvichaloupka.webnode.cz/200000623-bf48cc0431/100_2081.JPG
is identical to the species depicted there too.
If Christoph Schröder was right, logically
Delosperma 'Menoaneng Pass' should be Delosperma deleeuwiae.
It isn't as I could observe on a living plant.
For, the holotype and isotype of Delosperma deleeuwiae
http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000077166
strongly resemble acaulescent Delosperma ashtonii.
http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000077154
The receptacle and edges of leaves are hairy, i.e. the papillae
are elongated in short hairs.
The top of ovary is slightly concave=hollowed as in Delosperma ashtonii.
Stigmas are parallel in Delosperma deleeuwiae whereas spreading
in Delosperma ashtonii. Nectaries are rusty coloured
in the former, but their colour is not known to me in the latter.
By the way, the top of ovary of Delosperma sutherlandii
http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000077153
is distinctly convex=raised which can be checked at

Christophs D deleeuwiae looks a lot like what I have imported 10 years ago from South Africa. I have later on distributed these plants as Delosperma ´Silverhill`.

Martin,
The leaves are different in 'Silverhill'.

Perhaps you can share a better image. Northern Nursery pages are no longer working.

In several Delosperma species the germinating seedlings consist of an elliptic
formation consisting of fused horizontal cotyledons. Not so 'Hogan'. It has distinct
cotyledons positioned in an angle. Perhaps not in the genus.

Delosperma cooperii flowering in Kentucky today.
This is bone hardy here and certainly isn't troubled by heat and humidity....even at night. This is its third year and it just gets better with age.

....and two more

D.floribundum "starburst"
D. kelaidis Mesa Verde

[Great Moravian]

I wonder whether 'Kelaidis' and 'White Nugget' are patented outside the USA.

Image of Delosperma aff. hirtum by Marek Chaloupka. Collected in Lesotho, hardy, but winter wet
protection is necessary. Leaves persistent, forms congested clumps, flowers palest lavender,
nearly white, centre yellow, filaments yellow. Not hairy.

Hello,

any suggestions for this plant?

It is fully hardy here on a well draines site!

Leaves like D. nubigenum, flowers like D. cooperi?  That would be Delosperma 'John Profitt', presumed to be a hybrid between D. nubigenum and D. cooperi.

[Pauli]

Thanks Ian for the identification!

Have you noticed, that I have already posted a picture of a flowering D. deilanthoides from your seed!
I am very happy with them!
