Winterfat, also known locally by many other names, is a valuable shrub on winter ranges over much of the West.
Winterfat occurs from Canada throughout the western United States, including western Texas to northern Mexico. It grows in areas from near sea level in Death Valley to over 3,048 m (10,000 ft.) on high mountain ranges in central Utah. This species grows on a wide variety of soils, from alkaline to near neutral calcareous, that range from clays to sandy and rocky loams and rocky outcrops. It is quite drought-tolerant and dominates extensive ranges when average annual precipitation may be no more than 10 cm (4 in.).
Winterfat is a bushy-branched, semi-shrub. It is generally from 30.5 to 91 cm (12 to 36 in.) tall. Plants produce many erect stems, which are woody from the base to the crown. During the growing season, plants have an overall pale, bluish-green color. Dense, wooly hairs, which turn from white to pale rust with maturity, cover the twigs, leaves and branches. Leaves are narrow and about 2.5 cm (1 in.) long. Upon ripening, the seed heads have a cottony, attractive appearance.
The seed should be planted to a depth of 0.6 cm (¼ in.). Its uses include reclamation of disturbed areas such as mine sites, high-line highway and pipeline right-of-ways. Winterfat also makes a very attractive ornamental.
