Tree ID - Tree of Heaven lookalike - ?

slowjane CA/ Sunset 21April 21, 2014

For the last year I have thought this was a Tree of Heaven - a professional arborist I consulted agreed - my sister has a grove of them and they looked the same to me ...

But I just looked a little closer and thinking we've misidentified it

1) It doesn't smell bad
2) New growth is green
3) Leaves are serrated

It is deciduous - just started leafing out - leaves turned yellow before they dropped.

I've searched through many posts/website and have narrowed it to possibly Sumac, Black Walnut, Butternut - ? My best guess is Black Walnut but wondering if the folks out there agree?

It is a young tree - was maybe 3 feet tall last year in May - now taller than the house - part of why we thought it was ToH....

Here is a picture of the whole tree, bark, leaf structure, and leaf closeup.

We are in Los Angeles.

not a tree of heaven or a walnut.....tree of heaven have a single notch in the leaf toards the stem and walnuts do not have serrated leaves. Sumac in a possibility but not sure about the species. A big hint will be the fact that the tree has compound leaves.

How about a young pecan (Carya illinoenses)? Regardless, I believe that I would remove it from the side of the house while it is still considered small.

Thanks for the thoughts you guys. Yes, Tree_Man I think you are right. I had been afraid to cut it down if it was tree of heaven for fear they would pop up everywhere. At least now it's not so difficult to remove. Too bad it's so close to the house....

also - this shows the black walnut as having slightly toothed leaves - english walnut is smooth....

Here is a link that might be useful: black walnut vs. english walnut

First thought was walnut, though not sure they grow in Cali.

if you use stump killer ... properly applied to the cambian layer immediately after cutting flush to the ground ....things will not pop up everywhere ..

and you would avoid having to dig this out ...

and this would be a good place to do such.. as nothing should be planted that close to the house ... no matter the plant ... and you would avoid utilities.. if any ... dig safe
