Josephine horkelia

Family: Rosaceae · Type: perennial · Native

Conservation status: CNPS 2B.1

Josephine horkelia is a rare California native (CNPS 2B.1) perennial found in the northwestern Klamath Ranges of Del Norte County in vernally moist, rocky serpentine habitats at elevations of 300 to 800 meters. Flowering from April to June, this plant produces white flowers in small, head-like clusters with 5 to 15 blooms. Growing with glandular-hairy stems 15 to 30 centimeters tall in a tufted or rosetted form, it has a compact, gray-green appearance. Its compound leaves feature 2 to 5 leaflets on each side, each leaflet elliptic and less than 5-toothed, densely hairy and measuring 5 to 12 millimeters long. The plant forms a simple or few-branched caudex, creating a dense, low-growing cluster in its rocky serpentine habitat.
