Dombeya wallichii: Pinkball1

Edward F. Gilman and Dennis G. Watson 2


Nothing could be more attention getting than pinkball when in full bloom. Huge, pendent clusters of tightly-packed, 5- to 6-inch-diameter, pink flowers give much the impression of upsidedown corsages intermixed with large, coarsely-textured, light green leaves. Pinkball maintains a rounded form and can grow to 20 feet in height with an equal spread and makes a spectacular specimen planting or patio tree. It is usually grown as a shrub.

Use and Management

Growing rapidly in full sun to partial shade on a wide variety of soils, pinkball needs protection from frost and is not salt-tolerant. Flower heads fall from the tree, remaining pink for a number of days. The dried flower heads will need to be cleaned up for a neat appearance beneath the tree but otherwise it is a very low-maintenance tree. Plants can be watered until established and then forgotten except in the driest locations.

There are several hybrids available.

Propagation is by softwood cuttings which root quickly and easily.


Aphids, soft scale, nematodes, and sooty mold are minor problems for pinkball.


No diseases are of major concern.
