Grayleaf Willow

Scientific name

Salix glauca


The Grayleaf Willow is a deciduous shrub species that typically grows up to 1.5 m as a shrub, but under favorable conditions can become a 6 m tall tree. This plant may also be known by the common names: Gray Willow, Smooth Willow, White Willow, or Glaucous Willow. The bark is gray and smooth. The leaves are a glaucous green, alternately arranged, 3-5 cm long, narrow and elliptic shaped, and have silky white hairs. The flowers are short, densely haired catkins, which are cylinder flower clusters that appear in May. The flowers develop into whitish yellow seed capsules. As with many Willow species, this plant is very flood tolerant and hardy. This shrub is a valuable source of food for many wildlife species. However, Willow trees are also a preferred food and building material for beavers.
