Psidium littorale: Cattley Guava1

Edward F. Gilman and Dennis G. Watson2


This upright, multi-branched, evergreen shrub or small tree has many features which make it a popular landscape choice. Unfortunately, Cattley Guava has escaped cultivation and has infested ditch banks and other wild areas in south Florida, and its use should be tempered. Capable of reaching 25 feet in height but often seen at 10 to 15 feet, the thick, smooth, dark green, four-inch-long, leathery leaves nicely complement the smooth, grey-brown to golden bark which attractively peels off in thin sheets. The single, white, one-inch-diameter flowers have many prominent stamens and look like powderpuffs in miniature. The blooms appear heaviest in April but can open sporadically throughout the year.

Use and Management

The 1.5-inch-diameter, bright red, pear-shaped fruits ripen to a very dark red in July and are a popular treat - for people and wildlife. Birds, raccoons, and squirrels all love the delicious, sweet-tart, white flesh and will widely spread the small, grape-like seeds. The abundant, fallen fruits may be messy on hard surfaces such as walks and cars, and trees should probably not be planted along residential streets or over sidewalks or patios. It would make a good small boulevard or median street tree and accents an area with its well-shaped canopy and interesting trunk form. It combines well with other plants in a shrub border and provides both food and cover for wildlife.

Cattley Guava grows well in full sun or partial shade on a wide range of soils, including sand or clay, but fruit quality is improved on rich soils. Plants are drought-tolerant once established but benefit from a thick, organic mulch. Any necessary pruning should be done after fruiting. Pick the fruit for eating before the fruit fly larvae discover it.

Psidium littorale var. littorale , Lemon Guava, is slower-growing and has large yellow fruits with delightful, spicy flavor.

Propagation is by air-layerings or by seeds. Seeds germinate easily and rapidly. Seedling plants take seven or eight years to bear fruit.

Pests and Diseases

No pests or diseases are of major concern. Fruit fly larvae devour the fruit but do no harm to the tree.
