Karen is without a doubt among the most coveted azaleas for front foundation bed planting. It's cherished for position near the front door to call attention in the spring with its exquisite mass of color. Outstanding shrub for all beds and borders and will integrate with nearly every plant sharing the same requirements. Azaleas naturally thrive in the acidic soils beneath natural woodlands or ornamental groves of evergreen and hardwood trees. This is an essential of the Japanese tea garden as a symbol of spring, and is found in gardens throughout Asia.

Care Instructions
Thrives in humus-rich, acidic, moist, well-drained soils. Water deeply and regularly during the first growing season to establish an extensive root system; once established, water as needed to maintain evenly moist soil. Feed with an acid fertilizer after bloom. Keep roots cool with a thick layer of mulch.
History
Karen is a hybrid developed from the species, R. kaempheri, native to volcanic slopes of northern Japan. The species was introduced to the United States via Arnold Arboretum in the 1890s and various American breeders took up breeding domestic cultivars. This is among the Gable Hybrids, produced by Joe Gable who crossed R. kaempheri with R. poukhanense, then added evergreen R. maxwellii as well as a number of early hybrids into his breeding program. Gable introduced dozens of excellent varieties over a period of fifty years from 1920 to 1980, all developed at his nursery in Stewartstown, Pennsylvania.
