Which tree produces the long flat bean pods?

Which tree makes the long sort of flattish pods with the beans inside? (Not the Catalpa with the long round pods.)

A common one is honeylocust. I don't think those of less prevalent Kentucky coffeetree are so flattened-looking.

I agree - most likely honeylocust (Gleditisia triancanthos). Very commonly planted tree (esp. G. t. var. 'inermis' (the one without the thorns)).

Do you know which variety of HoneyLocust? I have a thornless honeylocust and it doesn't. But maybe it's too young a tree still. Forgot when I planted it. maybe 5-6 years.

Yep, that's likely still too young to be fruiting.

If yours was raised from seed fruiting is possible. If it was instead a grafted named form, significant fruiting is much less likely as nearly all modern cultivars have been selected in part for setting few fruits. Like the thorns the pods are considered a detriment when planting for amenity use.

Since this is a large-growing species it seems seed-raised trees might take many years to reach flowering age, this is common with other kinds of tall trees. Grafted cultivars now prevalent have the sexual maturity of the parent plant and are therefore likely to flower at a small size. Possibly this has produced an impression that it is normal for trees to bloom young.

My Honeylocust (22' tall) is only in its 5th season, but flowered fairly well both last season & this. However, no fruits, possibly because it has no nearby pollinator.

Although most likely the Honeylocust in zone 5a. The Mimosa also has that sort of bean-pod. The Mimosa is a smaller non-native tree with pink-ish flowers.
