Potentilla hickmanii (called Hickman's potentilla or Hickman's cinquefoil) is an endangered perennial herb of the rose family. This rare plant species is found in a narrowly restricted range in two locations in coastal northern California, in Monterey County, and in very small colonies in San Mateo County. This small wildflower, endemic to western slopes of the outer coastal range along the Pacific Ocean coast, produces bright yellow blossoms through spring and summer.
This species was formerly thought to be growing in Sonoma County but that population has been recently reclassified as another species, Potentilla uliginosa and is presumed extinct in that county.
This plant, along with many other threatened species in the northern California Floristic Province, has been designated as a species meriting protection by the U.S. Government, State of California, local governments and private conservation groups. These designations have led to blueprints for protection of Hickman's potentilla in the form of official endangerment classifications and a species Recovery Plan, the latter promulgated by the U.S. Fish and Wildlife Service.
Potentilla hickmanii is a long lived rosetted non-glandular flowering plant with a thick taproot. The stem is prostrate five to forty five centimeters long. Blooming occurs between April and August. The hypanthium is three to six millimeters wide, with yellow obchordate petals six to eleven millimeters in length. Up to ten inflorescences may present in a single organism. Filaments are typically 1.5 to 4.0 millimeters in length, while anthers are only about one millimeter in size; moreover, the pistils generally number about ten and the slender styles are about two to three millimeters long.
