Rhododendron viscosum, the swamp azalea,[1] clammy azalea or swamp honeysuckle,[2] is a species of flowering plant in the heath family Ericaceae.

Description[edit]

This deciduous shrub, growing to 2.5 m (8.2 ft) tall and broad, 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.

Cutivation[edit]

In cultivation in the UK, Rhododendron viscosum has gained the Royal Horticultural Society’s Award of Garden Merit.[2][3] 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 mould.
