This native plant has a lot of different names .. Black Snake Root .. Cohosh .. etc ..
I planted one on either side of the cedar arbor and the difference in growth between the two is stunning .. the left side is much taller and larger .. as is the Joe Pye .. there is one year difference in them .. but I'm wondering if that slight difference in sun exposure has that much of an impact .. the kiwi vine next to it also is slightly behind it's twin on the other side .. and both were planted in tandem .. so obviously something is up with sun exposure !
