My Sister calls it a Toby Tree. It grows extremely fast several feet a year and has extremely large leaves. They're bringing me one today to plant in my yard. We live in Pennsylvania. It's the first 3 pictures in the pDF file. Kathy
My sister tells me that this tree has long bean pods and not like the Pods I've seen for the Paulownia - Empress.
Guess I should have looked closer at all the leaves. Some info on Catalpa here http://www.hort.uconn.edu/Plants/c/catspe/catspe1.html .Probably invasive by seed. Could use "search" at top of this page for more info. There are a number of species.
