This looks like it should be an elm based on the leaf shape but the colors don't look right. Does anybody know what this is for sure? I took the picture in Ann Arbor MI near the Matthaei Botanical Gardens.

It's not an elm, it's a herbaceous plant..but I can't tell what it is based on this. The leaves have too much powdery mildew on them...and there's no flowers.

Perhaps someone else will have a better notion.

RE: Unknown Plant

its a horrible weed.. and it looks precisely the same down here in adrian mi ...

talk about a powdery mildew magnet ... lol ...

i dont ID my weeds.. i kill them ... but i hang here.. to find out ...

and its not a tree.. nor an elm ...

if i am not mistake.. for the ID gurus.. the seed head of it.. is at the bottom right ... must have been a healthy swath of them ...

i just mowed 3 acres.. i dont know if i can recall where it was out there.. if i can find it.. i will report back.. if that is not the seed head ...

Here's another picture of it.

RE: Unknown Plant

Verbena urticifolia, white vervain. It is native and tends to occur in disturbed areas.
