Catalpa is a Midwest native tree that grows 40 to 60 feet tall, with a narrow, open, irregularly rounded crown and spreading branches. It has large, heart-shaped leaves and large clusters of fragrant, white flowers. The long, interesting seed pods persist through the winter. Northern catalpa is very adaptable to adverse conditions, but has weak wood and branch structure.
