here are a few in our garden from last October,

really nice ones, fermi--lots of great colour! i suppose your problem is the opposite of ours--making sure you dont plant one that will take over the country ;) or have they managed to keep all of those out? i know in some places there are some very invasive species..not a problem here...
Lori S.:
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.
Fantastic array of plants, Fermi!
Luc Gilgemyn:
My experience with Delosperma congestum is that it is as tough as old boots ! Here it has survived anything the weather has thrown at it over the last 15 odd years.
(minimum on just a couple of occasions to -10-12°C - usually with no snowcover - obviously nothing compared to your conditions in Canada)
Delosperma cooperi is more vulnarable ... I lost some plants last Winter (min. -10°C) and others survived barely. After having removed dead and shriveled leaves this Spring, they recovered admirably. I see a number of seedlings have popped up also.
I always try to have some plants in different locations in the garden, because of the Summer colour they provide... and they're easily removed if they're in the wrong spot or get too big.
I wouldn't be without them. :)

if tags are correct, and they are just garden centre purchases, i have congestum and nubigenum..i agree there are foliage differences, but definitely subtle... i havent wintered them yet...
interesting on cooperi, i havent seen any suggestion of that much hardiness (except i vaguely recall a mention of a higher altitude collection)..i have heard of people losing it much farther south than us, but hard to weed out issues of wet from cold in some cases...
Jean-Patrick AGIER:
Hi Everybody,
Extraordinary pics Fermi!!!
Lori: how bright are your Delosperma basuticum & aff congestum!
I'm growing lampranthus on a sheltered balcony. In winter we have between -5°C and -10°C depending on the locality ( but winters prove a little milder then before ). Delosperma Cooperi grows freely everywhere in Lyon ( centre of FRANCE ) without protection and is rarely damaged by frosts. The Lampranthus ssp haven't been protected last winter and they survived. Delosperma Ashtonii & Delosperma congestum have proved hardy on the most exposed of my 2 balconies. But these plants are so easy to multiply either by seeds or by cuttings ( I always secure some cuttings in case of frost damage ). Some plants have a very showy silvery foliage ( Lampranthus ) which stay attactive all year.
I think all of you have documentation on Aizoaceae but there's one very interesting article on the Genus Delosperma in the September 2006 issue vol 74 of The Alpine Gardener ( members of the SRGC forgive me... )
