Rhododendron viscosum

swamp azalea, clammy azalea

Swamp azalea is likely the most fragrant of the native azaleas and despite the name, an average garden soil will do just fine. Ranging in color from white to pale pink, this species has a broad, open form, and thrives in our acidic New England soils.
