Tabebuia heterophylla: Pink Trumpet Tree1

Edward F. Gilman and Dennis G. Watson2

Introduction

Pink Trumpet Tree grows at a moderate rate from a slim pyramid when young to a broad silhouette, 20 to 40 feet tall. The palmately compound, green leaves are evergreen throughout most of its range but may be briefly deciduous as the new leaves emerge. The showy display of pink or white, bell-shaped blooms appears throughout the spring and summer and is followed by the production of long, slender seedpods.

Use and Management

Pink Trumpet Tree is well suited for use as a street tree or for other areas such as in parking lot islands and buffer strips where temperatures are high and soil space limited. They will create a canopy over a sidewalk when planted on 25 to 30 foot centers if they are properly pruned. Develop high, arching branches several years after planting by removing the lower, drooping branches. This branching habit may take several prunings to accomplish. Pink Trumpet Tree can also be used as a shade tree for a residential property near the patio or deck, or it can be planted to provide shade to the driveway. The tree will provide lasting shade plus the added benefit of a sensational seasonal color show.

Pink Trumpet Tree should be grown in full sun on almost any well-drained soil, wet or dry. Established trees are moderately salt-tolerant and highly drought-tolerant. This tree is reported to be more tolerant of urban conditions than the Yellow Trumpet Tree.

Propagation is by seed or by vegetative methods. Vegetatively propagated trees would help ensure that trees bloom at the same time. Seed propagated trees flower at different times.

Pests and Diseases

No pests or diseases are of major concern.
