@Yamadori knows trees. She spends most of her time with trees. I was hoping she'd come on this thread.
She says:
"It's not a sycamore with a fancy name. It's a Norway maple. Different botanically.
Sycamore - acer pseudoplatanus
Norway maple - acer platanoides
Two different species, both of which can be annoyingly invasive. The OP's one appears to be a Norway maple, but it also looks somewhat like a sugar maple (acer saccharum) as well, but that's unlikely."
