Also known as the snowbed willow, the dwarf willow is one of the world’s smallest trees, growing up to about two inches tall. Its tiny size helps it survive the extreme climate of the tundra. Apart from staying close to the ground to avoid the worst of the harsh winds, its leaves grow broad to maximize the amount of sunlight it receives.
This perennial shrub is partial to well-drained riverbanks and steep, rocky slopes. It produces flowers that range from red and pink to yellow and brown.
