About

Rhododendron polylepis is an upright, evergreen shrub to around 1.8 m with long, lance-shaped, glossy dark-green leaves. In spring, trusses of funnel-shaped, dark to rosy-purple flowers create a vivid and ornamental display. A rewarding and handsome rhododendron for a sheltered, moist, acidic garden.
