Hi, Can't figure this one out. It does not attain a height of more than about a foot around here....I assume the deer like it too much but this year I have found an effective way to protect some specimens and they have had a chance to leaf out. It is growing in a small patch of Appalachian woodland, N. VA. Leaf base is offset so I thought black walnut but the leaflet number is consistently odd and I understand walnut is even? Thanks!
