Facts on the Catalpa Tree

Overview

The catalpa tree is a species belonging to the Bignonia family of plants. A tree that undergoes a series of noticeable changes as the year progresses, the catalpa may grow to as high as 100 feet and have a spreading crown 40 feet wide.

Geography

The catalpa originally grew in just two regions of the country before people cultivated it extensively in other parts of the United States. The northern catalpa is a tree native to the central part of the Mississippi Valley and the southern type is native to parts of the Deep South.

Identification

The leaves of the catalpa resemble elephant ears with their heart shape. They often grow three to a stem, are as long as a foot, and sometimes get to 8 inches wide.

Flowers

In the spring, after the leaves develop, the flowers bloom on a catalpa. They are as long as 2 inches and up to 3 inches wide, with white petals splashed with yellow, purple and orange.

Pods

The flowers turn into fruit pods containing seeds; at first, the pods are green but eventually turn brown as the summer turns to autumn. These pods hang down from the catalpa tree, resemble long beans or cigars and can stay on the tree through the winter.

Expert Insight

Although the catalpa is a picturesque tree, a homeowner will have quite a job cleaning up fallen seedpods as well as the flowers in the summer and the leaves in the fall.
