Catalpa Speciosa

Western Catalpa

Catalpa speciosa is a large, fast-growing deciduous shade tree with a broad, rounded crown and large heart-shaped leaves. It is particularly valued for its spectacular early-summer flowers, enormous foliage, distinctive bean-like seed pods, and attractive mature form.

Large clusters of white, orchid-like flowers appear in late spring to early summer. The flowers are white with yellow and purple markings and are followed by long, slender, brown seed pods that can remain on the tree through winter. The enormous leaves provide excellent shade but can create considerable leaf and pod litter.

It performs best in full sun and moist, well-drained soil, but is adaptable to a range of soil conditions. Once established, it has good drought tolerance and performs reasonably well in urban conditions.
