Salicaceae

Slender, deciduous tree with a long, cylindrical trunk and rounded crown of ascending branches, usually 15-20 m high.

Leaves: 4-7.5 cm. in length, rounded, fine toothed with abrupt point on long-flattened stem. Shiny dark green on top, pale green below.

Fruit: Greenish capsule about ½ cm. in length. Appears in May or June. Arranged in catkins containing small tufted seeds, opening at maturing.

Bark: Smooth, pale green with waxy appearance on young trees, turning grey, rough and furrowed into long flat ridges with age.

Habitat: A variety of soils, but prefers well-drained, moist loams. Found throughout Newfoundland and southern Labrador.

General: A heavy, strong softwood, one of the most widely distributed trees in North America. Not of commercial importance to Newfoundland, but a favoured ornamental and a choice food for beaver. Often grows quickly on burnovers reproducing from root suckers, the main natural method of reproduction.
