Found this catalpa tree in Hershey, PA, but I need to know what species it is. Can anyone help? There aren't any flowers on it at this time.
Although very similar, Northern Catalpa has slightly larger leaves, flowers, and bean pods. You can examine the pods to tell the difference. See below link: http://treenotes.blogspot.com/2008/06/northern-and-southern-catalpas.html
Measure the diameter of the seed capsules: Over 1 cm = Northern Catalpa Under 1 cm = Southern Catalpa
