In North America, Halberd willow occurs in northern Alaska, the mountains of central Alaska, including the Alaska Range, and extreme northwestern Canada. It is most common near the Arctic Coast. Halberd willow also occurs in northern Europe and Asia, southward in the mountains of both.
This plant is present in at least 3 states/provinces in this country.
Halberd willow is a native, multibranched, spreading shrub typically between 3 and 6 feet (1-2 m) tall. It has small, simple, alternate, deciduous leaves. Male and female flowers occur on separate plants in 0.75- to 2-inch-long (1.5-5 cm), erect catkins. Halberd willow has a remarkable characteristic of plasticity; its growth form adapts readily to a wide variety of habitats.
Halberd willow flowers in late spring or midsummer (May-June). The fruit ripens soon after flowering, followed by seed dispersal in late July and early August.
