Hi Karen,
to the heuchera forum! Happy to have you here.
Do you have a large heuch collection? That sounds like an awful lot of work moving all those plants - hope you have some help. It's been pretty wet here too. First the snow started melting (and there was a lot to melt!) then it's pretty much been raining ever since. Tomorrow we're supposed to have a dry day too so I hope to get outside and check things out a bit better.
Carolyn, would not surprise me if all the new cross breeding weakens them. I would sure be disappointed if I lost them all in one winter.
