Swamp Azalea, Swamp Honeysuckle, White Swamp Honeysuckle, Clammy Azalea, Cory Azalea, Hammock Sweet Azalea, Deciduous Azalea, Very Late Season Rhododendron
Prized for its strongly-scented flowers and beautiful fall foliage, Rhododendron viscosum, known as Swamp Azalea, is a very appealing native to the swamps of the eastern United States, from Maine to Alabama and westward to Texas. This bushy, medium-sized, deciduous shrub bears funnel-shaped, white flowers, often tinged pink, with long slender tubes. Held in small clusters of 3-12 flowers, they bloom profusely after the leaves emerge in early summer and exude a strong clove-like perfume. The foliage of lustrous, elliptic, dark green leaves turns brilliant shades of yellow, orange, and purple in fall for a great colorful show. Exceptionally cold-hardy, this late-season Azalea can withstand temperatures as low as -20°F (-29°C). A wonderful landscape plant that deserves a place near a patio, deck, or living area, where its delightful fragrance can be enjoyed.
