We got this spindly tree from my sister-in-law who didn't know what it was.

It's about six feet tall in a large pot. The mature leaves are of a consistent size and are all close to two inches long.

It appear to be evergreen and has not suffered in light freezes. A plant ID app keeps saying it can't identify it.

A plant ID from phot web site said it was one of two kinds of Leguminosae, but the arrangement of the leaves is wrong. And the leaf shape is not quite right.

Interesting looking tree, any luck on the id?

I'm having trouble with my eyesight tonight and I can't tell in your photos if the leaves are opposite or alternate but something about it reminds me of Tree Senna (Senna corymbosa)

Opposite. This one looks very like it.

I haven't had it long enough to see it bloom or seed. But it looks right and is in the right range. Size it right. And there have been no other candidates. So pending bloom, I'm going to say that's it.

Local sources say it's perfect here in Central Texas, and there's a specimen in the demo garden at the ag extension office in the next county.

Thanks, you beat two plant photo ID apps and two web sites.

I don't know the plant, but I do know opposite vs. alternate.

The leaflets are in opposite pairs along that plant's leaf midribs (rachis), but the leaves are pinnate compound and arranged alternately along the woody stems of Senna corymbosa - which is a member of Fabaceae (Leguminosae).
