Mystery maple?

[j_walker]

I don't know what species of maple this is. I found it growing in mulch. Can enyone id it? It's about 3 years old.

Looks like a trident (Acer buergerianu) with the 3 pointed leaves .. Nice find

It doesn't look like the other tridents I have. I live on the edge of their hardiness zone as well. I'm not convinced it is, but it could be.

Can you post a comparison pic with your other tridents?

It could be a hybrid maple with the trident traits being more visible.

I'm not super familiar with maples in general, but it looks like you have 2 different styles of leaves on this maple. The leaves higher up will be your identifying leaves.

My silver maple which I am thinking is a hybrid, has two different leaves on it. The first flush is more rounded and hard to identify. The 2nd flush is very clearly a silver maple.

Acer ginnala.

To me that looks less like a trident leaf than the one your trying to identify

My guess is tatarian maple, Acer tataricum. I see them quite a lot here, the "Hot Wings" variety is pretty popular. Looks like they plant them in Pennsylvania too!

Very likely could be Acer ginnala too, just saw what @Mikecheck123 posted. Very similar leaves.

I got them from kaede bonsai-en so I know that they are tridents.

Definitely possible foe either. The parent tree is a smaller maple. Im thinking it's a hybrid of sorts.

It's definitely an Amur maple. I have a few as bonsai. They are invasive in Pennsylvania and the N.E. U.S. Having one pop up in mulch is a pretty standard way they arrive. They're tough and extremely winter hardy and produce a lot of seeds.

Leaf shape can be variable, but both pics you have provided of leaves fit Amur.

My vote goes for acer ginnala as well (Amur maple) I know that they're considered invasive in some parts of the country.

Are you saying my trident is not a trident?

The first two pics are amur. If you got your tridents from Matt O., they are most definitely tridents.
