A fast-growing tree, 10-60 ft., with an open crown often with several trunks growing out at angles from one root. Found in wet soil along streams and at the margins of ponds and lakes. Leaf blades up to 5 inches long, narrow and tapering to an elongate tip, margins finely serrate. Bright yellow-green twigs bear yellow-green catkins. Flowers inconspicuous, arranged in elongate clusters which appear in March and April; male and female flowers on separate trees. Seeds wind-borne on silky hairs. The bark is deeply furrowed.

This is the largest and most important New World willow, with one of the most extensive ranges across the country. In the lower Mississippi Valley it attains commercial timber size, reaching 100-140' (30-42 m) in height and 4' (1.2 m) in diameter. Large trees are valuable in binding soil banks, thus preventing soil erosion and flood damage. Mats and poles made from Black Willow trunks and branches provide further protection of riverbanks and levees. One of the lightest of all eastern hardwoods, it is extremely weak in a structural sense. Yet it has a strength of its own. When nails are driven into it, black willow does not split. Also a shade tree and honey plant.

Use Wildlife: The bark, tender twigs and buds are food for browsers such as deer, rabbits and beaver. Early season harvest for songbirds, waterfowl and small mammals.
Use Medicinal: The bark of the roots is intensely bitter and used to be an ingredient of spring tonics to purge the blood.
Use Other: The numerous uses of the wood include millwork, furniture, doors, cabinetwork, boxes, barrels, toys, and pulpwood. During the American Revolution, the wood of black willow (and of other willows) was made into fine charcoal, which was then used to make gunpowder. The young stems are very flexible and are used in basket and furniture making. The twigs can be split in half lengthways, sun-dried and used as the foundation of coiled basketry. The plant is usually coppiced annually when grown for basket making.

Propagation:
Black Willow are not very hard to propagate.
Make a fresh angled cut at the bottom (already angled) side of the cutting.
(Alternate Step: Place in water for 7-10 days for roots to form and then plant the cuttings. This will almost guarantee success!)
Using a rooting hormone is not necessary but will improve your chances.
Stick directly into the ground, coarse builder's sand or a well-draining potting mix.
