The Azalea group's Rhododendron 'Betty Anne Voss' is a lovely evergreen variation. This well-behaved shrub has dense foliage and a dense, spreading habit, making it a good choice for acid borders, forest edges, and rockeries. The lush, glossy foliage displays its candy-pink, double blooms perfectly during May. Height: 100 cm (39). Spread: 120 cm (48).
