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.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
