Range
Eastern North America, from New Brunswick and southern Ontario west to Minnesota, and south to northern Florida and Texas.
Description
It is a medium-sized deciduous tree, the largest North American species of willow, growing to 33–98 ft tall, exceptionally up to 148 ft, with a trunk 20–31 in diameter. The bark is dark brown to blackish, becoming fissured in older trees, and frequently forking near the base.
The fruit is a 0.20 in capsule which splits open when mature to release the numerous minute, down-covered seeds. The leaves turn a lemon yellow in the fall. It is typically found along streams and in swamps.
Another name occasionally used for black willow is "swamp willow", not to be confused with Salix myrtilloides (swamp willow). It is also commonly mistakenly referred to as a "weeping willow". That species is native to Asia.
