Swamp Azalea is a loosely upright native shrub that can be deciduous or evergreen with simple green leaves that turn red in fall if deciduous. The very fragrant, sticky white flowers bloom from late spring into summer. Deadheading spent flowers can extend the bloom season. Best grown in part sun and rich, moist to wet well-drained acidic soils.
Note: All parts are highly toxic if ingested.
