Swamp azalea is native to the eastern and southern United States. It prefers swampy lowland habitats with a uniform level of soil moisture. Plants: Woody, evergreen or deciduous shrubs are 3-5' (91-152 cm) around, rarely reaching 8' (2.4 m) and (by some accounts) up to 12' (3.7 m) in width. They have a somewhat gangly habit. Leaves: Alternate, lustrous, dark green, narrow, obovate to oblong-obovate, with blunt or short-pointed tips. In the fall, leaves turn orange or maroon. Flowers: White to pale pink, 1¼-1¾" (3.2-4.4 cm) long, in clusters of 4-9. Each flower consists of a long, narrow, very sticky tube, flared at the end into a corolla of five fused petal-like lobes. Five stamens extend beyond the flower, with dramatic flair. Flowers have a sweet, musky, clove-like aroma—said to be the most aromatic of all azaleas. Blooms from May to July. Fruits: Capsules are ¼-¾" (7-20 mm) × ⅛-¼" (3-7 mm), in dark brown clusters. Edibility: Poisonous Online References:
