How big is the dwarf willow?

The dwarf willow, also known as Salix herbacea, is one of the smallest tree species in the world, typically growing to a height of only 2 to 6 inches (5 to 15 centimeters). It is a low, creeping shrub that often forms dense mats in cold, arctic, and alpine environments. Its small size allows it to withstand harsh conditions and strong winds.
