Sidalcea oregana is a species of flowering plant in the mallow family known by the common name Oregon checkerbloom. [1]
It is native to western North America from British Columbia to California to Utah, where it grows in a number of moist habitat types, such as marshes and meadows. The plant is somewhat variable in appearance, and the species is divided into a few subspecies; some authors also recognize varieties within subspecies. In general, this is a perennial herb growing to maximum heights well over one meter from a woody taproot.
Sidalcea oregana is usually hairy in texture, the hairs thick and bristly toward the base of the stem. Most of the leaves are located low on the stem, basal or on long petioles. [2] Their blades are usually deeply divided into lobes (see image at left); upper leaves may be divided further into leaflets.
The inflorescence is a dense or open spikelike raceme of many flowers. Each flower has five pink petals up to 2 centimeters long, usually notched at the end, and a central tube of reproductive parts (see flower closeup image). [3]
Subspecies include:
It is a larval host to the West Coast lady. [12]
Sidalcea pedata, also called birdfoot checkerbloom or Big Bear checkerbloom, is a rare and endangered perennial herb of California. It blooms between May and July. However, it is an endemic species of California and only occurs in few places in the San Bernardino Mountains, primarily at Bear Valley, Bluff Lake. It grows at 1500–2100 m elevation in moist meadows to open woodlands and the unique pebble plain habitat of the area. Since Big Bear Valley is a resort destination, the birdfoot checkerbloom is threatened by development, vehicles and grazing.
