Don't know if you have noticed but the blooms on 'Pacific Spring Frost' are much larger than the the majority of sempervivum. Almost struck me as being a tetraploid because of its larger size. However, there are tet arachnoideums that are no bigger than the diploid ones. Anyway, I self pollinated the stalk to see what sort of seedlings it might produce. It is a nice one anyway but the blooms were especially impressive.
