Calliandra surinamensis: Pink Powderpuff1

Edward F. Gilman and Dennis G. Watson2

Introduction

This large, multiple-trunked, low-branching, evergreen shrub has silky leaflets that are glossy copper when new, turning to a dark metallic green. The profuse, fragrant bloom is the main reason for its popularity, with big puffs, two to three inches across, of watermelon pink and white silky stamens, produced during warm months.

Use and Management

With rapid growth in sandy soils and full sun, powderpuff bush will respond favorably to regular watering while young but should require no special care once established, except an occasional pruning to keep it within bounds. Pinching new growth increases the number of branches and enhances flower display. Powderpuff bush may be used as a tall (5- to 6-foot) flowering hedge and is often seen as a small, flowering specimen tree with the lower branches pruned off. Powderpuff can grow to about 15-feet tall when pruned into a small tree. The long, arching branches form an attractive canopy suitable for patio or container plantings.

Although plants are damaged by freezing temperatures, they grow back from the base in the spring in USDA hardiness zone 9.

Propagation is by seed or cuttings.

Pests

While usually pest free, powderpuff bush can be occasionally infested by mites, caterpillars, or other chewing insects.

Diseases

No diseases are of major concern.
