Eriogonum ovalifolium is a species of wild buckwheat known by the common name cushion buckwheat. It is native to western North America from California to Alberta, where it is a member of many plant communities in varied habitats, including the sagebrush steppe and alpine regions.[1]
In general, the species is a tough perennial herb which forms mats in gravelly soil or amongst rocks and produces erect inflorescences up to 35 centimeters (14 in) in height, blooming from early to mid-summer.[1] The flowering stems are leafless.[1] The pale green to gray leaves at the base of the plant are rounded and woolly and have petioles.
The clumps of flowers are yellow, light red or pink, purple, or white.[1]
Variety nivale is found at subalpine and alpine elevations west of the Rocky Mountain crest. The leaves are densely covered with white wooly matted hair.
Varietiesedit
There are four[2] to eleven[3]varieties of this species. They include:
Eriogonum ovalifolium var. williamsiae, the steamboat buckwheat, is known only from the Steamboat Hills near Reno, Nevada.[4] It is also a federally listed endangered species, and threats to it have been reduced but the populations are still quite small.[4]
