Tabebuia impetiginosa: Purple Tabebuia1

Edward F. Gilman and Dennis G. Watson 2


This briefly deciduous tree reaches 15 to 20 feet in height and has a fairly open canopy. Branching is often sparse allowing turf and other sun loving plants to grow beneath the canopy. The dark green, palmately compound, five-inch-long leaves are joined in late winter or early spring by the showy, trumpet-shaped blooms, appearing in dense, rose-pink to purple, terminal panicles. Trees will have a better form if trained to a single trunk and staked until they are six to eight feet tall, at which time they can be allowed to grow naturally.

Use and Management

Use this small tree in an area where any small tree can be used. It might be best to locate it in a shrub border or other out-of-the-way place since the canopy is quite thin, even in full sun. It is probably not as well suited for specimen planting as the other tabebuias.

Purple tabebuia should be grown in full sun on almost any well-drained soil but trees respond especially well to rich soil. Established trees are highly drought-tolerant.

Propagation is by seed, cuttings, or layering. Plants flower at an early age.

Pest and Diseases

No pests or diseases are of major concern.
