Korean azalea (Rhododendron yedoense var. poukhanense) is a low-growing azalea covered with pink-mauve flowers in spring and orange to red fall color later in the season. Like other plants native to Korea, this species is winter hardy in many parts of the Upper Midwest, including the Chicago region. The cultivar is a hybrid of the straight species (yedoense) and the naturally occurring regional variant (var. poukhanense).
