Western Catalpa

Catalpa speciosa

Cultivars: 'Aurea'

Western catalpa is a medium to large deciduous tree valued for its large heart-shaped leaves and showy summer flowers. It develops a broad, rounded canopy that provides dense shade and a bold tropical look in the landscape. In early summer, clusters of white flowers with purple and yellow markings appear, followed by long, slender seed pods that add seasonal interest. Its coarse texture and large foliage make it a standout specimen in residential and park settings. Dwarf forms such as ‘Nana’ are used where a smaller ornamental tree is desired.

Care Instructions

Catalpa thrives in full sun and tolerates a range of soils, including somewhat dry conditions. It has medium water needs during establishment and becomes moderately drought tolerant once mature. Pruning is often needed to maintain structure and remove weak or crossing branches. Winter protection is generally unnecessary in Rocky Mountain climates. With proper placement and occasional maintenance, it provides bold foliage and summer flowering interest.
