I live in Fort Smith AR. We moved from Zone 5 to Zone 7 and I hold had to swot up a lot of unusual plants. I have tried to research and identify this tree online near no success. I own one large tree and one small one on my property but own not seen anywhere else around here. I don't know what shape it would typically get because it is growing near a lot of other tree's and shrubs. It is currently something like 30 to 40 ft tall. Every spring it have a lot of street light purple flowers that grow on the underside of the leaves. The leaves are large. They are bipinnately compound. They are alternate and are serrated or toothed. They remind me of a trumpet vine palm leaf. It is a fast grower and the immature bark is a smooth grey. The elder bark is slightly grey and brown. It is a bit rough but not heavily ribbed. Standing back a bit it looks similar to shaky lines running up the tree. It is not tree of heaven. Any philosophy?
