The
eye-catching Pink Trumpet ‘Tabebuia heterophylla’ Tree
grows at a reasonable 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.
Moreover,
Pink Trumpet Tree should be grown in full sun on just about 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. As
far as no Pests and Diseases are of major concern. CP
