Rhododendron yedoense (syn. Rhododendron poukhanense), the Korean azalea, is a species of flowering plant in the family Ericaceae, with a disjunct distribution in northern Myanmar, Yunnan province in China, South Korea, and northern Kyushu island of Japan.[1] Hardy in USDA zones 4 through 9, it is recommended as a hedge, and has above average resistance to the root rot that often afflicts azaleas.[2] Rhododendron yedoense f. poukhanense is a major parental contributor to many modern hybrid azaleas.[2]
