A few posts back there was a post about basswood flowers. Ooops, wrong tree. This is not a flowering basswood. It's a catalpa. Below are some real basswood trees and soon to be flowers. What fooled me was the large size of the leaves, which the bottom photo shows on the volunteers from a basswood tree. The leaves on the full size tree are smaller.
I deleted the previous post as I didn't have the time then to correct it, and we wouldn't want any misinformation on the interwebs.
