Calophyllum inophyllum: Beauty Leaf1

Edward F. Gilman and Dennis G. Watson2

Introduction

This upright, pyramidal, densely foliated evergreen tree can reach 60 feet in height in the forest with a 30- to 40-foot spread, but is generally much smaller because it grows slowly. This is an asset in tropical landscapes, where many other plants grow so fast. Greenish, showy, .75-inch, very fragrant flowers are produced on eight-inch racemes in the summer. The round, yellow, 1.5-inch-wide fruit contains a single seed with a nutlike kernel that may be poisonous. The seven-inch-long, glossy, dark green, stiff, leathery leaves have numerous, distinct parallel veins at right angles to the midrib. The trunk has light grey, shallowly ridged bark, and the wood is valued for boat building and cabinet work.

Use and Management

Beauty leaf makes a good specimen, street, parking lot, or shade tree and is both wind and salt tolerant, making it especially useful for coastal locations. It becomes twisted and contorted when exposed to constant wind, creating an interesting specimen. Beauty leaf is sometimes used as a tall hedge or windbreak around tennis courts and similar places. It could be used more often as an urban street tree. Remember that the golfball-sized fruit is poisonous and hard, and this could be undesirable in the landscape under some circumstances. The trunk grows to about two feet in diameter.

Beauty leaf thrives in full sun or partial shade on any well-drained soil. It is not tolerant of freezing temperatures.

Propagation is by seeds or cuttings.

Pests and Diseases

No pests or diseases are of major concern.
