Tabebuia heptaphylla: Pink Trumpet Tree1

Edward F. Gilman and Dennis G. Watson 2


Pink trumpet tree produces a wonderful specimen tree, reaching a height of 50 feet and is covered with terminal panicles of pink to rose-purple, two-inch-wide, showy blossoms in spring. There are few, if any, other flowering trees which can match the beauty of this tree in bloom! Flowers stand out nicely because there are no leaves on the tree during flowering. They contrast nicely against the light grey bark. The palmately compound leaves bear five leaflets, each about two-and-one-half inches long.

Use and Management

Pink trumpet tree would make a nice tree for planting along a boulevard or residential street where there is plenty of soil space for root development. Prune major limbs so they remain about one-half the diameter of the trunk so they remain well secured to the trunk. This is a tree you will want to keep around, once you see it in flower.

Pink trumpet tree should be grown in full sun or partial shade on rich, well-drained soil.

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

Pests and Diseases

No pests or diseases are of major concern.
