Northern Catalpa 15 Gallon

Northern Catalpa — 15 Gallon

(Catalpa speciosa)

 

Tree Description

The Northern Catalpa is a bold, fast-growing native shade tree known for its large heart-shaped leaves and showy clusters of white flowers that bloom in late spring. The blossoms resemble small orchids, with delicate purple and yellow markings that create a striking display against the tree’s broad green canopy.

This tree develops a wide, spreading crown that provides excellent shade, making it a great choice for larger yards, parks, and naturalized landscapes. After flowering, the tree produces its distinctive long bean-like seed pods, which remain on the tree through fall and winter and add seasonal interest.

These 15-gallon trees establish quickly and grow rapidly, making them an excellent choice for homeowners looking to add a unique and fast-growing shade tree to their landscape.
