Northern Catalpa

Northern Catalpa (Catalpa speciosa)

Northern Catalpa (Catalpa speciosa) is a fast-growing deciduous tree known for its bold tropical appearance, heart-shaped leaves, and showy clusters of white, orchid-like flowers. With its large canopy and striking visual presence, it brings shade, seasonal interest, and unique character to parks, large landscapes, and naturalized settings.

Distinctive Features

Catalpa speciosa features enormous leaves up to a foot long, giving it a lush, tropical feel. In late spring to early summer, upright panicles of white flowers with yellow and purple markings create a dramatic floral display. After blooming, long, bean-like seed pods develop and persist through winter. The coarse texture and upright branching pattern add bold structure year-round.
