The weather did a number on all three of the plants I have, but I do have one bloom right now on one of the plants. I'm going to put a knee-hi over it to see if I can catch some seeds. I hope I get more blooms though.
Hellebore seeds usually can be harvested in late May/early June. Good luck!
I know there was a conversation about this somewhere last year, and someone mentioned putting the leg of a pair of panty hose on the bloom to catch the seeds. So I have my fingers crossed. I figure if I put it on sometime this month, I'm guaranteed to get something.
