Sidalcea hartwegii is a species of flowering plant in the mallow family known by the common names valley checkerbloom and Hartweg's checkerbloom. [1] [2]
The plant is endemic to California, where it grows in the Sacramento Valley and adjacent foothills of the California Coast Ranges to the west, and of the Sierra Nevada to the east. [2] It can grow in oak woodland and grassland habitats below 600 metres (2,000 ft), sometimes on serpentine soils.
Sidalcea hartwegii is an annual herb that produces a slender stem up to 30 centimetres (12 in) tall, mostly hairless with occasional branching hairs. The leaf blades are deeply divided into five to seven narrow linear lobes.
The inflorescence is a clustered panicle of four to six flowers, each with five purplish pink petals about 2 centimeters long. The bloom period is May and June.
Sidalcea candida, the white checkerbloom, prairie mallow or white checkermallow, is a wildflower found from Nevada to Wyoming and south to the southern part of New Mexico. The plant grows to three feet, and is also known as wild hollyhock. Its flowers are about one inch wide with five petals. It is found mostly in mountain meadows and along streams. It flowers between June and September.
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.
