The Kurume azalea is a hybrid of Rhododendron Obtusum and Rhododendron Kiusianum, both native to the island of Kyushu, the southernmost island of Japan.
Most of the Japanese Azaleas make very successful bonsai. Even very old plants produce spectacular flowers. The Kurume azaleas have wonderful flowers, but perhaps not as showy as the Satsuki Azaleas, and are usually smaller, with more solid colors, leading to a more refined appearance. The flowers of Kurume azaleas are small about 1cm (1/2in) across. Most flowers are single.
