Plant Type
Tree
Catalpa bignonioides ‘Aurea’ is a fast-growing deciduous tree valued for its brilliant foliage and distinctive form. It develops a broad, rounded canopy with coarse branches and large tropical-looking leaves. Often used as a specimen tree or shade provider, it adds dramatic color contrast in gardens and parks.
Mature Height
8–12 meters/ 26–40 feet
When mature, Catalpa bignonioides ‘Aurea’ typically reaches 800–1,200 cm (8–12 meters), or about 26–40 feet tall, with a similar spread. Its wide, open crown and rapid growth make it ideal for creating quick shade, while its luminous foliage enhances visual interest throughout the growing season.
Light Requirements
Partial shade – Full sun
This catalpa cultivar thrives in full sun to partial shade. Full sun enhances the vivid golden color of the leaves, while too much shade can cause them to fade to green. It tolerates a range of light conditions but performs best in open, sunny positions with good air circulation.
Water Requirements
Moderate
Catalpa bignonioides ‘Aurea’ prefers moderately moist, well-drained soil but tolerates occasional drought once established. Regular watering during dry spells encourages healthy growth and vibrant foliage. Avoid waterlogged conditions, especially in heavy clay soils, as excessive moisture can stress roots and reduce the tree’s vigor and longevity.
Cold Hardiness
-20°C (-4°F)
Catalpa bignonioides ‘Aurea’ is hardy to approximately -20°C (-4°F), thriving in USDA Zones 5–9. It tolerates cold winters and recovers well from frost damage. In colder regions, young trees may need shelter until established, but mature specimens are resilient and well-suited to temperate climates.
