Marbled wild-ginger is a rare (CNPS 2B.3) California native perennial found in northern Del Norte and Siskiyou counties in the Klamath Ranges, growing in moist forests and exposed rocky slopes at elevations of 200 to 1,800 meters. Flowering from April to June, this plant produces olive-brown flowers with dark red-maroon tube interiors marked by scattered dark hairs. Growing in dense clumps with deep, nearly vertical rhizomes, it develops stems that support distinctive leaves with striking white markings along the major veins. Its leaf blades are predominantly green with margins bearing erect-spreading hairs, creating a marbled appearance that gives the plant its distinctive character. The flowers emerge on nearly erect peduncles, with calyx lobes standing upright and revealing an intricate internal coloration.
