Invasive Maples? Please help identify ...

topieAugust 8, 2009

Just wondering if anyone can help identify these maples. Both of these trees are growing near our yard. Not sure if one or both are Norway maple or not.

Tree One (the leaf on the left) doesn't appear to be producing seed pods at the moment, although it's hard to tell because this tree has a lot of English ivy and poison ivy growing up its trunk and it's difficult to get very close to the tree.

Tree Two (the leaf on the right) is producing seed pods right now (early August). It's leaves are a lighter green than Tree One.

Didn't see any milky sap when I plucked the leaves off.

Can't recall either of their fall colors at the moment.

There was a third tree in this area that our town cut down that the tree cutters said was a Norway maple.

One or both of these trees is having lots of babies all over. The two trees are close together, so it's hard to tell which tree is making the saplings, but I think it's Tree One.

If anyone can help identify, thanks in advance!

The first looks like Norway maple. Try pulling off another leaf and wait a little while to see if it exudes milky sap.

The second one is sugar maple. Can tell by the shape of the leaf and the samaras.

Thank you very much for your reply. I'm pretty sure that Tree One is a Norway Maple. I'm glad to know the other one is a native Sugar Maple. I had the feeling that's what it was, but wanted to ask just to be sure.

Well, at least there is one native tree out there in our "maple area".

Thanks again.

I agree with the ID from lycopus. There should be milky sap from Norway Maple, but it can be hard to extract at times. Try squeezing the leaf stem to force out some sap.
