Native plant nurseries.
Medium tree with tall trunks and a dense crown composed of slender upright branches. Trunks 6-15 inches in diameter. Bark reddish-brown, mottled, thin, separating into large scales and covered with breathing pores (lenticels). Leaves compound, leaflets 2-6, usually 4, firm, dark green and shiny above, 2-5 inches long.
Typically 25-35 feet in height; to 45 feet in South Florida. Taller than broad, except when young when the plant can be quite bushy.
Growth Rate:
Moderate to slow.
Monroe County Keys north mostly along the coast to Collier and Volusia counties; West Indies, Mexico and Central America. For a digitized image of Elbert Little's Florida range map, visit the Exploring Florida website.
Moist, well-drained sandy or limestone soils, with humusy top layer.
Nutritional Requirements:
Moderate to high; grows best with some organic content and may languish in nutrient poor soils.
Salt Water Tolerance:
Low; does not tolerate long-term flooding by salt or brackish water.
Salt Wind Tolerance:
Moderate; grows near salt water, but is protected from direct salt spray by other vegetation.
Drought Tolerance:
Moderate; generally requires moist soils, but tolerant of short periods of drought once established.
Light Requirements:
Light shade to full sun.
Flower Color:
White, with an orange disk in the center.
Flower Characteristics:
Semi-showy. Fragrant. Dioecious, with male and female flowers on different plants, or polygamodioecious, with a few flowers of the opposite sex or bisexual flowers on the same plant.
Flowering Season:
Winter-summer; peak in spring.
Orange or reddish-brown 1/2" wide berry turning dark purple when ripe. Summer to fall.
Wildlife and Ecology:
Provides significant food and cover for wildlife. Attracts pollinators and fruit-eating birds.
Horticultural Notes:
Can be grown from seed with some difficulty, but seedlings establish well under parent plants. Seedlings can be transplanted without difficulty, but roots are often slow to establish and staking may be necessary. Best grown in light shade while young.
An attractive medium tree with dense foliage maintained close to the ground for many years. The wood is very hard, heavy, and durable and much used for crafts and construction. The bark and berries are used to make a homemade ink-like substance in the West Indies. See also the Florida Wildflower Foundation's Flower Friday page.
