Shrubs
Rhododendron x 'Robleg'
Autumn Angel® Encore® azalea
Pure white flowers contrast with glossy, dark green leaves on a compact evergreen shrub. Its modest size suits containers and low foundation plantings. Repeat flowering extends its usefulness beyond spring, though this selection needs a warmer, protected setting in our region.
