Silky horkelia is a California native perennial ranked 4.3 by CNPS, found in the northwestern Klamath Ranges in Del Norte County, growing in dry, rocky serpentine clay within open chaparral or pine forest at elevations of 180 to 1,200 meters. Flowering from June to August, this plant produces white to pink-tinged petals in delicate, open clusters with flowers often slightly separated. Growing with silvery, tufted stems 15 to 40 centimeters tall and a few-branched caudex, it develops a distinctive appearance with dense silvery hairs. Its leaves are remarkable, typically 3 to 10 centimeters long with approximately 15 crowded leaflets on each side, each leaflet divided almost to the base with narrow elliptic lobes. The plant's compact, silvery form and densely clustered, finely divided leaves make it a distinctive member of serpentine landscapes.
