Sweet azalea is a beautiful native deciduous shrub prized for its intensely fragrant white flowers in late spring to early summer and its striking red-to-orange fall foliage. It thrives in moist, acidic, well-drained soil rich in organic matter and performs best in dappled shade or morning sun with afternoon shade. Mulch the root zone generously to retain moisture and maintain the cool, acidic soil conditions it requires.
