Catalpa x erubescens is known for its showy, fragrant, pink flowers that bloom in late spring or early summer. The flowers are trumpet-shaped and can grow up to 2 inches long. The tree also has large, heart-shaped leaves that can be up to 10 inches long.
The hybrid catalpa is hardy in USDA Zones 5-9 and prefers full sun to partial shade. It can tolerate a range of soil types, including clay, loam, and sand, but prefers well-drained soil. The tree is relatively low-maintenance and is resistant to many common pests and diseases.
Catalpa x erubescens is a popular ornamental tree and is often used in landscaping and as a shade tree. It is also sometimes planted as a windbreak or for erosion control. The wood of the tree is strong and durable, and has been used in the past for fence posts, railroad ties, and furniture.
