Willows, also called sallows and osiers, of the genus Salix, comprise around 350 species of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions.
Salix alba, the white willow, is a species of willow native to Europe and western and central Asia. The name derives from the white tone to the undersides of the leaves.
Salix purpurea, the purple willow, purpleosier willow, or purple osier, is a species of willow native to most of Europe and western Asia north to the British Isles, Poland, and the Baltic States.
Salix amygdaloides, the almond leaf willow or peach leaf willow, is a species of willow native to central North America east of the Cascade Range. It can be found in southern Canada and the United States—from western British Columbia to Quebec, Idaho, Montana and Arizona to eastern Kentucky.
Salix babylonica is a species of willow native to dry areas of northern China, but cultivated for millennia elsewhere in Asia, being traded along the Silk Road to southwest Asia and Europe.
Salix nigra, the black willow, is a species of willow native to eastern North America, from New Brunswick and southern Ontario west to Minnesota, and south to northern Florida and Texas.
Salix reticulata, the net-leaved willow, or snow willow, is a dwarf willow, native to the colder parts of Europe, North America, and Northern Asia. It is found in the western United States, including the Sierra Nevada and Rocky Mountains. In Europe it extends south through the Carpathian Mountains and Alps to the Pyrenees and the mountains of Bulgaria and North Macedonia. It is common in Canada, Greenland and Finland, and present but rare in Scotland.
Salix lasiolepis is a species of willow native to western North America.
Salix lucida, the shining willow, Pacific willow, red willow, or whiplash willow, is a species of willow native to northern and western North America, occurring in wetland habitats. It is the largest willow found in British Columbia.
Salix exigua is a species of willow native to most of North America except for the southeast and far north, occurring from Alaska east to New Brunswick, and south to northern Mexico. It is considered a threatened species in Massachusetts while in Connecticut, Maryland, and New Hampshire it is considered endangered.
Argyresthia pygmaeella is a moth of the family Yponomeutidae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775 from a specimen found near Vienna, Austria
Salix bebbiana is a species of willow indigenous to Canada and the northern United States, from Alaska and Yukon south to California and Arizona and northeast to Newfoundland and New England. Common names include beaked willow, long-beaked willow, gray willow, and Bebb's willow. This species is also called red willow by Native Americans according to The Arctic Prairies Appendix E by Ernest Tompson Seton.
Salix geyeriana is a species of willow known by the common names Geyer's willow, Geyer willow and silver willow. The type specimen was collected by the botanist Karl Andreas Geyer, for whom it was named. Its conspicuous, yellow flowers begin to bloom as early as March, to as late as the end of June.
Salix brachycarpa is a species of flowering plant in the willow family known by the common names barren-ground willow, small-fruit willow and shortfruit willow.
Desert riparian is a North American desert vegetation type occurring in the bottoms of valleys, canyons, and other watercourses that have water at or near the surface most of the year. The visual character is of large, lush, perennial green trees surrounded by dry desert vegetation and soil coloration. The area may be in a patch surrounding a spring such as an oasis, or in a strand following the course of water flow, such as a bosque. The soil in this biome is typically moist and ranges from rocky and sandy to silty alluvium. This biome has seasonal variation, with hot, dry summers and cool, moist winters. Precipitation mostly occurs during the winter, and ranges from 8 to 25 cm each year. It is contrasted with the desert dry wash vegetation type, in which water at or near the surface is lacking most of the year, such as arroyos.
Salix eriocephala, known as heart-leaved willow or Missouri River willow, is a species of willow native to a large portion of the temperate United States and Canada.
Salix pyrifolia, the balsam willow, is a species of flowering plant in the family Salicaceae, native to Canada, and the north-central to northeastern United States. A shrub, its leaves emit a balsam-like fragrance. It is available from commercial suppliers.
