I started these Paperbark Maples from seed.. and of course not many sprouted.. only 5… The ones that did, do not have the same leaves as the parent plant.. I have NO OTHER MAPLES in my area except for red Japanese maples that did not have any seeds, so I am sure these are the Paperbark maple seeds I planted in the row.
The pictures are 1st year plants taken late summer..
Could these be juvenile leaves?? As these leaves do not resemble the parent tree.
I suppose this coming Spring may tell the story but I am wondering if this is what they look like as young plants?
Paperbark Maple seeds have notoriously low viability (particularly from isolated cultivated plants). Amur Maple is fecund, though, and invasive in parts of Canada; maybe yours blew in from a nearby seeding specimen?
