Rhododendron (Rhododendron spp.)

Rhododendron (Rhododendron spp.), also known broadly as rhododendrons or rosebays, encompasses a diverse group of evergreen and deciduous shrubs grown for their spectacular spring blooms and architectural foliage. With thousands of cultivars and hybrids available, rhododendrons offer options for every landscape, from compact foundation beds to expansive woodland gardens.

Distinctive Features

Rhododendrons vary widely in size, with dwarf selections maturing at 2 feet and larger types reaching over 10 feet. Their leathery, often glossy leaves are evergreen in most cultivated varieties, offering year-round structure.
