The dwarf willow, scientifically known as *Salix herbacea*, is a small, low-growing shrub found primarily in Arctic and alpine regions. It typically reaches heights of only 5 to 15 centimeters, making it one of the smallest willows. This plant thrives in cold environments, often growing in rocky or tundra areas where other vegetation struggles to survive. Dwarf willow has small, rounded leaves that are usually less than 2 centimeters long. It produces tiny catkins, which are the flowering structures of willows, in early spring. This species plays a crucial role in its ecosystem by providing habitat and food for various wildlife, including insects and birds.
