Short greyish purple leaves covered with fine down. Slow growing and slow to bloom.

In zone 9b, semp was planted in stone container. Easily retained shape and form in uncovered container last winter. Fuzzy texture colored a frosty pale rose in spring. What a robust little sempervivum!

What I have seen marked "Engles" should actually be 'Engle's 13-2'. It is similar but not identical to 'Purdy's 90-1' and 'Aymon Correvon'. When they did the Dalton project to determine the correct names, the thought was that 'Aymon Correvon' ( then recently renamed from "Correvon's hybrid") is the correct name for all three. Helen Payne STRONGLY disagreed with this decision. Since then she was proven right. At the Dalton project, plants going into bloom were quickly removed so that none of the stock plants could be contaminated by seedlings. However, the blooms of these cultivars are different, especially comparing 'Aymon Correvon' to the other two. 'Aymon Correvon' is also BIGGER than the other two. 'Engle's 13-2' has the most compact rosette and leaf shape, with 'Purdy's 90-1' a bit more elongated.

All three are from a montanum X wulfenii cross, probably F1, as that hybrid tends to be sterile or nearly so. I was looking at my notebook from my youth and in '68 I tried to raise seedlings from both 'Engle's 13-2' and 'Purdy's 90-1' and did so each year for 4 years with NO seedlings. My notebook says "seed looks odd, lots of chaff". Both montanum and wulfenii are diploids and their chromosomes must be enough different that it's impossible or nearly so for them to produce normal gametes. Each year here in Oregon I let the bees try to cross 'Aymon Correvon' and each year I dutifully plant the seed, noting "more chaff than seed" still. Despite planting all the open pollinated seed from 4-6 stalks each year not a single seedling has germinated. 'Greenwich Time' which is montanum X calcareum cross (again two diploids) has netted me ONE seedling. It is a nice one though!

Hope that helps!

Kevin
