The leaves of the Catalpa tree are large and heart shaped, creating a lush canopy of light green or yellow-green leaves. The tree can reach up to 40 feet tall and its branches are wide and spreading. In late spring to early summer, the tree erupts with showy clusters of white flowers. In the fall, the Catalpa tree produces long seed pods that hang from the branches. Worms tend to find this specimen as a great area to crawl, making them perfect bait for those who like to go fishing. (USDA Zones 4-8)
