This genus contains over one hundred and fifty species, indigenous from the farthest North of the Alaskan timber-fine to Mexico and from Norway to the Levant. The Willow loves a sheltered valley and a moist soil by the side of a stream where its bunches of rootlets may be seen floating on the water.

Salix alba (the White Willow) and its variety vitellina (the Golden Willow) and Salix babylonica (the Babylonian Weeping Willow) are among the best for ornamental planting.

Propagate, in November, December or January, by placing a cutting, of any size or length, one-third of its length in any soil; give it plenty of water.
