Some kind of sumac, or what?

Hi Meg,

that looks like a black walnut sapling to me.

I have to yank 'em up all the time.........stupid squirrels.

Why do they gotta plant it right up next to my house?? Grrr.

A sumac, I'm sure - we have a forsythia clump at the side of the parking lot and sumac grows in there too.

Is that the same as poison sumac?

That is ailanthus 'tree of heaven'. A pretty little tree w/ more keys than a maple & propagates readily. They look similar to the sumacs, but are not toothed. The have that tell-tale notch toward the base of the leaf.
