Sidalcea oregana

Oregon checker mallow

Family: Malvaceae · Type: perennial · Native

Oregon checker mallow is a California native perennial found in montane meadows, conifer forests, and open woodlands at elevations of 500 to 2,500 meters. Flowering from June to September, this plant produces soft pink to dark rose-pink flowers 10 to 20 millimeters long in dense, spike-like clusters. Growing with clustered stems 30 to 150 centimeters tall that are glabrous or coarsely hairy at the base, it forms a woody taproot with a branched crown. Its leaves vary from lower broadly crenate or lobed blades to upper leaves with 5 to 7 narrow, deeply divided lobes, ranging 3 to 10 centimeters wide. The fruit segments are smooth, 2 to 3 millimeters long with a tiny 0.3 to 0.7 millimeter beak.
