Cornaceae (Dogwood Family)

Synonym(s): Nyssa uniflora

USDA Symbol: nyaq2

USDA Native Status: L48 (N)

Large aqautic tree with swollen base, long, straight trunk, narrow, open crown of spreading branches, and large, shiny leaves. Water tupelo is a narrow-crowned, flood-tolerant, deciduous tree, 50-100 ft. tall, with a buttressed base. It is very symmetrical and pyramid-shaped in its early years, but develops an irregular form with age. Large, glossy, dark-green leaves turn yellow in fall. Fruit ripens to black.

This aquatic tree was named Nyssa after one of the ancient Greek water nymphs or goddesses of lakes and rivers. The name Tupelo is from Creek Indian words meaning swamp tree. The spongy wood of the roots has served locally as a substitute for cork in floats of fish nets.
