Asarum lemmonii (Lemmon's wild ginger) is a native California herb in the Aristolochiaceae family, recognized by short, strongly reflexed calyx lobes and reflexed peduncles.

Lemmon's wild ginger is a California native perennial found in southern Cascade Range and Sierra Nevada Foothills in Powellton, Butte County, inhabiting shady wet places at elevations of 1,000 to 1,900 meters. Flowering from May to September, this plant produces red flowers with white inner tube, the calyx lobes 0.8 to 1.5 centimeters long and strongly reflexed during flowering. Growing in loose spreading mats with horizontal rhizomes near the soil surface, it forms a low, interconnected ground cover. Its leaves are uniformly green, forming a backdrop to the distinctive reflexed flower peduncles. The plant spreads through its near-surface rhizomes, creating gentle, interconnected patches in its shaded, moist habitat.
