I have Cimicifuga racemosa which is in flower now, C. americana, C. japonica which is about to flower. I have a third plant (actually dozens of them) which grows as tall as C. racemosa and starting to flower. The obvious difference is that the leaves are huge, as much as 9-10 in (20-25 cm) wide. Is this a different species or a form of racemosa?
