Welcome!

Can you add some photos of the entire tree, trunk and branches?

It looks like a Robinia. Are the twigs bristly at all, like this:

Robinia hispida

If not, then perhaps Robinia pseudoacacia, black locust.

No need to hold on.

I don't think there is any question that this is Black Locust - Robinia pseudoacacia. This species does not always flower as a relatively young plant. I'd also say that a gardener not noticing doesn't always mean that the plant didn't perform.

It is a commonly occurring suckering/colonizing species that tolerates a wide range of soils and growing zones. It has pinnate compound leaves, often with a grayish/bluish cast, that are arranged alternately along the stems. As branches mature, you will notice rose-like thorns at the base of where the compound leaves attach to the stem. With age, this leguminous species produces fragrant flower clusters in late spring/early summer which bees love. From these flowers are formed the trademark flattened pods of the Fabaceae clan, containing relatively small hard black seeds. This species grows all across the Valley here. The wood is extremely rot resistant, and makes good posts as well as other uses.

If you are intent on a re-evaluation of this identification, then provide more information. Two images of plant parts are not much, if you expect absolute certainty from observers.

You haven't shown the entire plant yet, nor its growing situation. You should take pictures of each part of the plant - trunk, bark, leaves (pinnate compound) top and bottom, leaflets, rachis, petiolules, buds, stems, arrangement of leaves along stems, spines, thorns, lenticels, flowers, seeds, and any other plant part you can think of. Evidence of insects or disease presence can often be a positive identifier - like the Black Locust leafminer trails evident in your first picture.

Post them here, and your concerns will be allayed.
John
