Rhododendron viscosum
Also called Clammy Azalea, Swamp Honeysuckle, Texas Azalea
Swamp azalea is a deciduous shrub native to the eastern United States, growing to about 2.5 m with fragrant white, pink-flushed early summer flowers. It thrives in moist, acid soil in dappled shade.
Rhododendron viscosum, the swamp azalea, clammy azalea or swamp honeysuckle, is a species of flowering plant in the heath family Ericaceae. A deciduous shrub, it grows to 2.5 m (8.2 ft) tall and broad. It is native to the eastern United States. It has rounded matt green leaves. In early summer it produces funnel-shaped white flowers flushed pink. The flowers have prominent stamens and are strongly fragrant.
It is hardy down to −20 °C (−4 °F) but like most rhododendron species requires a sheltered position in dappled shade with acid soil that has been enriched with leaf mold. In cultivation in the UK, Rhododendron viscosum has gained the Royal Horticultural Society's Award of Garden Merit.
