Winter Snow is an intermediate growing rhododendron hybrid with showy bright blooms from Harold Greer, making it a bit of a collectible cultivar. Pale magenta buds start showing in March and usually open around April to a vibrant snowy white, sometimes with a bit of red in the throat. It is quite lovely. 

Plant in well-draining soil with full sun to partial shade. Winter Snow has a relatively even growth habit and reaches around 4' tall x 4' wide at maturity. Hardy to -10°F when protected from windchill.
