Salix nigra (Black Willow) is a species of willow native to eastern North America, from New Brunswick and southern Ontario west to Minnesota, and south to northern Florida and Texas.

Flowers

It is a medium-sized deciduous tree, the largest North American species of willow, growing to 10-30 m tall, exceptionally up to 45 m, with a trunk 50–80 cm diameter. The bark is dark brown to blackish, becoming fissured in older trees. The shoots are slender, variable in color from green to brown, yellow or purplish; they are (like the related European Salix fragilis) brittle at the base, snapping evenly at the branch junction if bent sharply. The foliage buds are small, 2–4 mm long, with a single pointed reddish-brown bud scale. The leaves are alternate, long, thin, 5-15 cm long and 0.5-2 cm broad, usually somewhat falcate, dark, shiny green on both sides or with a lighter green underside, with a finely serrated margin, a short petiole and a pair of small stipules. It is dioecious, with small, greenish yellow to yellow flowers borne on catkins 2.5-7.5 cm long in early spring at the same time as the new leaves appear. The fruit is a 5 mm capsule which splits open when mature to release the numerous minute, down-covered seeds. It is typically found along streams and in swamps.

Salix gooddingii (Goodding's Willow) is sometimes included in S. nigra as a variety, as S. nigra var. vallicola Dudley; when included, this extends the species' range to western North America. However, the two are usually treated as distinct species.
