Compact stature, royal color—Autumn Majesty® Encore Azalea lives up to its name with masses of petite, ruffled, semi-double dark purple blooms that arrive in spring and return in waves through summer and fall. Hardy to USDA Zone 6A, this purple Encore azalea keeps its bright green, evergreen foliage all winter on a naturally rounded, compact habit, bringing four-season polish to borders, beds, and containers.
