I bought this little untagged acer palmatum (I think it's acer palmatum) from a neighborhood nursery that sells maples mostly from Buchholz in Oregon. It was on sale at the end of the season in October 2017. Thought maybe it was Osakazuki but the leaves are not the same as that one. The mature leaves are a little distinctive--amoenum and the lobes are kind of club shaped. Was thinking that maybe someone would recognize them. I have only 34 maples and it matches none of them and have studied Vertree's book but not sure of anything. It has been a really hardy little tree and has been in the ground through last winter. Seems to be thriving in 6b. So if anyone has an inkling of what it is I would appreciate hearing! Thanks so much!
