The Northern catalpa. Some people HATE this tree. It has big leaves and seeds to rake up. I don't see the problem though. The seed pods are light and dry when they fall and disappear when the lawnmower goes over them.
Mr. Dirr says: "Limited value in the residential landscape because of coarsness; has a place in difficult areas but the use of this and the following species (he names the other catalpas) should be tempered."
Mine is right in front of my house and provides wonderful shade. And when it blooms in late spring, it is a sight to behold!
