The black willow has large roots that run along the surface of the ground, offering attractive sites for nesting. Many of Canada's 75 species of willow originally come from Europe. The black willow, the largest of all, is one of the few willows that grow to tree size. It can reach 20 metres in height and be truly immense because willows often divide into several trunks right at the base of the tree.
Willows reproduce more easily than any other tree.
In colonial times, willow branches were made into charcoal. The tree is appreciated today for its attractiveness and for its highly developed root network that binds the soil along banks. Leaf Fruit Leaves, alternate, simple, toothed, long and straight. Fruits, small hairy capsules, on drooping catkins.
