With some 900 or so registered cultivars, it is pretty hard for even JM experts to assign a name unless there are some unique distinguishing characteristics. With just generic green leaves, it would be foolish to even attempt a guess........it could be one of dozens. Or even the straight species, Acer palmatum.

regardless of its cultivar name.. it should be treated like any other A. palmatum ...

if it is the straight species ... there may have been a graft failure back in time ... but i cant see that in your pix ...

there is a JM forum .... but i have no idea how active it might be ...

According to the employee I spoke to at the garden shop they said it was from seed not a graft

If it was grown from a seed, then it is just the straight species, Acer palmatum. Named forms are never seed grown...they can only be propagated asexually.

Marcell Deeb-Lubsey,

You have a nice Japanese Maple, Acer palmatum. Get it in the ground as soon as you can. It's probably gonna have brilliant fall colors next month.
