Oemleria cerasiformis, also known as the Osoberry and 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.
