Hoary azalea is a stunning native deciduous shrub that bursts into fragrant pink blooms in early spring, often before its leaves emerge. Plant it in part shade with acidic, well-drained, humus-rich soil — conditions that mimic its natural woodland habitat in the southeastern US. Avoid waterlogged soil and harsh afternoon sun to keep the foliage healthy and the blooms vibrant each season.
