I saved seeds from it; planted some and shared some, but no germination yet here, and I haven't heard back from anyone else.
I could split them up, but I'm too chicken to do the whole clump.
I might do what I did last year and just dig a few away from an edge, then instead of sharing them out, plant them myself. I can't recall what the baby corm situation was like last year but they'd probably multiply quicker if I separated them. I really just don't know when is the best time, nor how to do it properly. I hesitate to be too experimental because these are somewhat expensive to replace, especially when they're doing so well as they are.
