Cunningham’s White is an excellent choice for those seeking a hardy plant with a white bloom. This rhododendron is robust and strong, yet provides brightness with its white flowers that are enhanced with a beautiful pattern on the dorsal petal that ranges from pink to yellow. Blooms mid-season and does well in partial shade to full sun. Can grow to about 4' tall, this hybrid is hardy to -15°F when protected from windchill.
