The Satsuki Japanese azaleas are believed to have originated several hundred years ago from natural crosses between Rhododendron species now called R. indicum and R. tamarae. These compact, low-growing, evergreen shrubs have small leaves that vary widely in shape. The Satsuki azalea hybrids seem to be able to handle a little more sunlight than most azaleas, and are hardy in USDA Hardiness Zones 7b through 9. The usually pink flowers, often multicolored in various patterns, bloom from late spring to early summer. The Satsuki hybrid azaleas are beginning to bloom now at the US National Arboretum, and can be found in and around the Frederic P. Lee Azalea Garden in the Azalea Collection.
