The '''Dwarf Willow''' (''Salix herbacea'', also known as the '''Least Willow''' or '''Snowbed Willow''') is the most common of a group of tiny creeping [[willow]]s (family [[Salicaceae]]). It is the smallest tree in the world. It is adapted to survive in harsh arctic and sub-arctic environments, and has a wide distribution on both sides of the [[Atlantic Ocean|North Atlantic]], in arctic northwest [[Asia]], northern [[Europe]], [[Greenland]], and eastern [[Canada]], and further south on high [[mountain]]s, south to the [[Pyrenees]], the [[Alps]] and the [[Rila]] in Europe, and the northern [[Appalachian Mountains]] in [[New York]], [[United States]]. It grows in [[tundra]] and rocky [[moorland]], usually at over 1500 m altitude in the south of its range.
It typically grows to only 1-6 cm in height and has round, shiny green [[Leaf|leaves]] 1-2 cm long and broad. Like the rest of the willows, Dwarf Willow is [[plant sexuality|dioecious]], with male and female [[catkin]]s on separate plants. As a result the plant's appearance varies; the female catkins are red-coloured, while the male catkins are yellow-coloured.
