Eriophyllum lanatum, with the common names common woolly sunflower and Oregon sunshine, is a common, widespread, North American plant in the sunflower family. Eriophyllum lanatum is native to western North America, commonly growing in many dry, open places below 10,000 feet (3,000 m) in elevation. It prefers full sun and well-drained soil, but it also grows on rocky slopes and bluffs.
It is most common across California, in chaparral, oak woodland, mixed evergreen forest, and yellow pine forest and other conifer forests, grassland, and sagebrush scrub habitats. It also grows north through Oregon into British Columbia and east through Idaho into Wyoming, and through Nevada into Utah. Its range reaches south into Mexico in Baja California state.
Eriophyllum lanatum is a perennial herb growing from 1 to 2 feet (30 to 60 centimeters) in height. The woolly sunflower grows in well-branched clumps. Both stems and leaves may be covered with a woolly gray hair, but some plants lack this hair. The hairs conserve water by reflecting heat and reducing air movement across the leaf’s surface. The hairs impart a dusty gray color to the plant. (Wikipedia) Photo credit: By Walter Seigmund CC by SA 3.0.
