Nyssa sylvatica, widely known as Black Gum, Sourgum and Black Tupelo, has a dense conical crown, and nearly horizontal branches. Grows from 20 ft to 50 ft, with a trunk of 1 ft to 5 ft in diameter.
Smooth, waxy, dark-green summer foliage changes to fluorescent yellow, orange, scarlet, and purple in fall. Flowers are small and insignificant. Black Gum has a flowering habit that is polygamodioecious, meaning that some plants have mostly male flowers while others have mostly female flowers, with most plants having a few perfect hermaphrodite flowers. The nectar from the flowers is sought after by bees. Berries are small and blue. A handsome ornamental, and shade tree, its juicy fruits are loved by birds and mammals alike.
Site in a permanent location because its long taproot makes it difficult to transplant later. It is tolerant of drought, heat, dry and wet soils, and is moderately salt tolerant.
