Azalea & Rhododendron

The great spring set-piece of the Southern garden. Azaleas and rhododendrons cover themselves in bloom so completely that for a few weeks the shrub disappears behind the flowers, then settle back into quiet, useful evergreen and deciduous shapes.

Rhododendron viscosum var. glaucum glaucous swamp azalea, sticky white fragrant summer flowers.
Glaucous Swamp Azalea
Rhododendron viscosum var. glaucumGlaucous Swamp Azalea

The glaucous swamp azalea is a native deciduous shrub of the wetland South and the eastern seaboard, a blue-leaved form of Rhododendron viscosum, the widespread swamp azalea that ranges from the Gulf Coast north into New England. The variety glaucum sets the plant apart with foliage washed in a soft blue-green, most striking on the leaf undersides, which flash pale as a breeze turns them. Where many shrubs falter, this azalea thrives in the consistently moist, even boggy ground of swamps, marshes, and stream banks.

Rhododendron 'Addison' native azalea hybrid, large trusses blending yellow, pink, and white.
Azalea, Hybrid 'Addison'
Rhododendron x alabamense 'Addison'Azalea, Hybrid 'Addison'

'Addison' began as a chance seedling of the Alabama azalea, Rhododendron alabamense, and grew into something none of the parents quite predicted. Surely a hybrid, though the exact parentage remains unknown, the plant carries large, dense, dome-shaped terminal clusters that blend shades of yellow, pink, and white in a single truss, a multicolored effect striking enough that the selection first went by the name 'Stunning'. Charles Webb, a good friend of Woodlanders, spotted and selected the seedling in Florida, and the plant now carries the name of one of his young granddaughters.
