Answer: Fraxinus pennsylvanica Summit is a male tree with an upright pyramidal growth habit and a straight central leader. The slightly glossy dark green leaves turn an excellent yellow in autumn. It typically grows 45' high and 25' wide. You can prune to keep these trees smaller. Because of their potential mature size, I think yours are planted too close to the foundation of the house. I'd move them now, while they're still young!
