Mark,
It's exciting to hear that you're trying some emasculated crosses. I doubt I'll be crossing heuffelii that way again any time soon, too much hassle, those flowers essentially have to be destroyed to access the pollen and I tend to prefer other species of sempervivum anyway. I tried self crossing 'Jade' in 2018 and then tried self crossing 'Lemon Sky' in 2019, neither situation yielded results. I am currently raising a grand total of ONE heuff seedling, the sole survivor from a bee seed batch off 'Lemon Sky'. This year I put roller blooms and heuff blooms together and let the bees work them, I'll be most interested to see the seedlings from the nixonii 'Jowan' which I included in the jovibarba bloom grouping as well as H. 'Bros'.
There's a small family of rollers from a 2018 self cross in my seedling bed now, I'm seeing some variation in color and size in that group, I have a slightly larger, tip-less, pale green I like.
pietwerkman,
it'd certainly be interesting to see your heuff seedling patch. If you got the seed from Erwin I'd bet there are some interesting combinations in there.
Goodluck,
