About Wild Ginger (Asarum caudatum) Asarum caudatum (British Columbia wild ginger, Western wild ginger, or long-tailed wild ginger) is native to rich moist forests of western North America from British Columbia to California and as far east as western Montana. Within California it is found primarily along the coast from Santa Cruz County northward. In spring, it develops distinct hirsute (hairy) cup-shaped, brown-purple to green-yellow flowers which terminate in three long gracefully curved lobes, often concealed by leaves. The long rhizomes give rise to persistent reniform (kidney/heart shaped) leaves. Leaves are found in colonies or clusters as the rhizome spreads. The leaves emit a ginger aroma when rubbed.

In the garden this plant must have regular water and virtually no direct sun.
