Rhododendron viscosum
swamp azalea
Notes:
Native to swamps and wetlands from the coast to the mountains. Humid air required. Wet soil tolerance is conditional on excellent drainage (hence the application of two tags that are usually mutually exclusive). Clay tolerance is debated (USDA, of all sources, vs. JerseyYards.org).
Very late-blooming among the native azaleas, but not as late as R. prunifolium. Fragrance is spicier than that of R. atlanticum, akin to cloves; also usually taller.
All parts poisonous.
