Does it resemble any of the other heucheras?
I believe this one is a cross Heuchera x Tiarella = Heucherella. This is a good grower for me. Tiarella 'Iron Butterflu' X Heuchera 'Breeder's Choice' are the parents. A Terra Nova intro. in 1999. I have take many cutting off mine.
You are so right. This is a heucherella and not a heuchera. Take a close look at the tag.
