Chrysophyllum oliviforme: Satinleaf1

Edward F. Gilman, Dennis G. Watson, Ryan W. Klein, Andrew K. Koeser, Deborah R. Hilbert, and Drew C. McLean 2

Introduction

Reaching a height of 45 feet and a spread of 25 feet in an oval form, satinleaf is a medium-sized tree noted for its unusually beautiful foliage. The evergreen, 4-inch-long leaves are a glossy, dark green above and a glowing, bright copper color beneath, providing a beautiful, two-toned effect when breezes cause the leaves to flutter. Leaves in some respects resemble those of the brown-back southern magnolias. This Florida native makes an attractive freestanding lawn specimen or blends well in a shrubbery border or naturalized landscape. It could be tried as a street tree or parking lot tree. Use it cautiously since it can be severely damaged at 32°F and below. The trunks are rather showy because they are covered with thin, light reddish-brown, scaly bark. Small, inconspicuous flowers are followed by small, sweet, purple or black fruits.

Use and Management

Satinleaf should be grown in full sun or partial shade on fertile, well-drained soils. Plants should be mulched and watered faithfully, although they are able to withstand occasional drought. The tree has not been widely planted but should make a good, durable urban tree in USDA hardiness zones 10b and 11. Trunk and branch structure is good, making this a clean, long-lasting tree.

Star apple, Chrysophyllum cainito, closely related, bears leaves of similar decorative quality and is grown for its larger (up to four inches long), more edible fruits.

Propagation is by seed, or semi-hardwood cuttings under mist.

Pests and Diseases

Caterpillars will occasionally chew the leaves, gall mite can deform leaves, and leaf notcher chews leaves.
