Sidalcea oregana var. calva
Also called Oregon Checker Mallow, Oregon Checkermallow
Oregon checkerbloom (Sidalcea oregana var. calva), also called Wenatchee Mountains checker-mallow, is a rare perennial herb in the mallow family, native to only a few sites in Washington's Wenatchee Mountains and listed as endangered. It is not commonly grown, and the key to growing it is to mimic its native dry, open mountain meadow conditions with full sun and excellent drainage.
Sidalcea oregana var. calva, the Wenatchee Mountains checker-mallow, is a very rare flowering plant variety that occurs only in five locations in the Wenatchee Mountains of Chelan County, Washington, United States. The plant has been placed on the Endangered species list. As of 2004, the population of the species was 11,000 individual plants.
Sidalcea oregana var. calva is a perennial herb in the mallow family Malvaceae. The species has a stout taproot that branches at the rootcrown and gives rise to several stems that are 20 to 150 centimeters (8 to 60 inches) tall. Plant stems vary from glabrous (lacking hairs and glands) to pubescent (hairy) or stellate (with star-shaped hairs) below and are finely stellate above. The leaves are somewhat thick and fleshy with long petioles (leaf stalks).
