I haven't had time to check on this bed till now. Around the squash, there is this plant growing. I had to move soil from the woods so I don't know what seeds could have mixed in there.




Thank you for the assistance!!

Kinds looks like a pecan to me!

Oh, this is in Ottawa Michigan!

It sure looks like Carya of some sort. How about Carya illinoiensis?

Do the leaves have an unpleasant odor if you crush them? Because it looks a lot like Tree Of Heaven (Ailanthus altissima) to me.

If the the leaves don't smell bad, there are several things it could be, but it's a bit hard to tell just by the leaves.

Could be a species of hickory (Carya, same genus as pecans, but more common in Michigan)
Could be a sumac. If so, it's most likely Staghorn Sumac (Rhus typhina)
Could even be Black Walnut (Juglans nigra), but that doesn't look quite right for that.

Leaf shape, and leaf venation are very similar to Fraxinus quadrangulata ..

Notice how the veins loop back onto each other ..

Maybe Elderberry?

The leaves of those are the right shape, but both Elderberry (Sambucus) and Ash (Fraxinus) have an opposite leaf arrangement. I can't see it clearly enough to be certain, but the plant in the picture seems to have alternate leaves. Most of its leaflets are opposite (or at least close), but the leaves themselves appear to be alternate.

I thought the leaves were not quite opposite too, but if you look at some of them in the second photo you can see they are opposite, I think! The angle seems to be giving a different impression.

I pulled them all off the bed, they did have an unpleasant odor. I might be going back to the woods where I got my soil to look at what trees are over there. Thanks again!
