USDA Symbol: NYSY

USDA Native Status: L48 (N), CAN (N)

Tree with a dense, conical or sometimes flat-topped crown, many slender, nearly horizontal branches, and glossy foliage turning scarlet in autumn. An attractive, variable-shaped deciduous tree, black tupelo grows 30-60 ft. or taller, with horizontally spreading branches. A bottle-shaped trunk forms if grown in shallow standing water. Smooth, waxy, dark-green summer foliage changes to fluorescent yellow, orange, scarlet and purple in fall. (Trees in warmer climates may not be as colorful.) Berries are small and blue.

A handsome ornamental and shade tree, Black Tupelo is also a honey plant. The juicy fruit is consumed by many birds and mammals. Swamp Tupelo (var. biflora (Walt.) Sarg.), a variety with narrower oblong leaves, occurs in swamps in the Coastal Plain from Delaware to eastern Texas.

Conditions Comments: This is a wide-ranging tree, found in a variety of habitats, so plants of local ecotype are necessary to ensure success. It is slow-growing. This species tolerates drier sites than N. aquatica and also tolerates poor drainage. Black gum transplants poorly due to a fleshy, non-fibrous root system. Move up to 4 in. caliper trees in the spring before onset of growth. Black gum does not age gracefully and is occasionally troubled by insect and disease problems.
