i took a jm cutting last year it took root fine came off a garnet maple that was grafted. it was a branch little over 1/8 dia and all year it looked like a std green jm 5 pointed leaf. took root fine the buds started popping this year about a week ago one leaf has 5 points like last year the rest look like a green laceleaf variety 7 points. i know this branch wasnt grafted cause it was right at groung level on the trunk stock. whats going on with it?
