Hey, I am new to Sempervivums and plants in general, but picked up a Sempervivum Arachnoideum "Arctic White" and am inlove with these plants.
From my own research, it seems that hybrids like mine can only reproduce via offsets, and not from their seeds because the seeds they produce would only be from the mother species. If this is the case, what should I do when the time comes that they flower? I don't want a bunch of "standard arachnoideums" germinating in my collection. Is this how it works? Will they only produce seeds when you physically cross pollinate them? Thanks!
