i was all ready to dig this up until i saw the base of it. the base looks pretty big for a weed, unless the previous homeowner just cut it back for years instead of digging it up. could it be a plant they cut back for other reasons?
sorry...don't know how to post more than one pic at a time...
I just went out and double checked against the trees growing in my yard. This is a black walnut.
Besides the fact that you probably don't want a tree that close to the house, black walnut roots, nut hulls, and leaves weaken and/or kill many other plants and trees:
Disclaimer: I can't tell a black walnut from an English walnut or a hickory. Hopefully someone more knowledgeable than I will confirm your ID.
I would have said walnut. Too many leaflets for a hickory.
I agree - Black Walnut or the very similar Butternut. It's a tree, you don't want it up against your walkway.
I've read about that juglone toxicity too, but I sure don't see any bare areas near the walnuts around here. And the dayliies and other stuff growing around the sapling in the pictures don't look too unhappy.
I just looked at the article again and realized that daylilies are listed as Juglone tolerant.
Thanks everyone! The plants around it do seem to be fine with it around but it is growing close to the house so I will have to remove it. Now that I know what it is, maybe I can find another place for it.
