Description: Medium to large tree with broad, rounded, dense crowns composed of wide-spreading branches. Trunks are usually short, soon branching, 6-18 inches in diameter. Bark grayish or reddish brown, divided and peeling. Leaves dark green above, paler beneath, 3-5 inches long, thin, rough above. Temperate deciduous, usually losing its leaves in the winter.

Dimensions: Typically 30-40 feet in height in South Florida; to 58 feet in Florida. As broad as tall or broader.

Growth Rate: Fast.

Range: Eastern North America west to Texas and south to Miami-Dade County and the Monroe County mainland. For a digitized image of Elbert Little's Florida range map, visit the Exploring Florida website. Note: Little's map shows the main range of this ending in northern Miami-Dade County with a disjunct population presumably representing Royal Palm Hammock in Everglades National Park. In fact, the natural range of this continues from northern Miami-Dade throughout most of the Miami Rock Ridge and into the park.

Salt Water Tolerance: Low; does not tolerate 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.

Flower Color: Greenish-white.

Flower Characteristics: Inconspicuous on long slender catkins. Partly dioecious, but with sufficient male flowers present on female trees to ensure reasonable fertilization. Pollination is by wind.

Flowering Season: Winter-summer; peak in early spring.

Fruit: Compound juicy berry, about 1" long, turning purple to black when ripe. Mostly late spring. Edible, sweet.

Wildlife and Ecology: Provides food and cover for wildlife. Many species of birds and other animals eat the fruits.
