Oemleria cerasiformis, also known as the Osoberry an Indian Plum, is the sole species in genus Oemleria. It is a shrub native to the Pacific coast and ranges of North America, from British Columbia, Canada to Santa Barbara County, California, U.S.A. . It is among the first plants to leaf out and flowers early in the spring. It reaches a height of 1.5–5 m and has lance-shaped leaves 5–12 cm long. Native Americans ate them, made tea of the bark, and chewed its twigs to use as a mild anesthetic and aphrodisiac .
