Dombeya spp. Tropical Snowball1

Edward F. Gilman 2


A native of the tropical parts of Africa, tropical snowball is grown more for its flower display than anything else (Fig. 1). The coarse-textured foliage is simple with shallow or deep palmate lobes. Bright pink or red flowers are prominently displayed on the new growth in the summer and sporadically throughout the year. Some types have white flowers.

Use and Management

Snowball is most often used as a specimen in a shrub border or near the corner of a building. Its beautiful flowers make this a premium shrub for locating in any part of a sunny landscape. Flower number is reduced in partial shaded locations.

Tropical snowball grows fast and adapts to a wide variety of soils. Several fertilizer applications each year help keep leaves dark green all year long. Some micronutrient deficiency symptoms appear in soils with a pH above 8.0. Regular applications with appropriate fertilizers prevent symptoms from appearing.

Pests and Diseases

Aphids and scales often infest the foliage and stems. Sooty mold often follows. Soil borne nematodes can stress the plant by reducing the size of the root system.
