Rhododendron viscosum, known as Swamp Azalea or Swamp Honeysuckle. After discovering this beauty a few days ago, I returned for some setting sun shots. This is a solitary bush close to the shoreline.
A Monograph of Azaleas:
"Rhododendron viscosum was apparently first observed by John Banister, an English missionary who sent a drawing of it to Dr. Compton, Bishop of London. Dr. Compton communicated it to Plukenet, who published it in 1691 in his Phytographia. The plant was introduced into England apparently in the first half of the 18th century by John Bartram, who sent seeds or plants to Peter Collinson, but the exact date is not known."
