About this plant
Rhododendron x 'PJM' is a broadleaf evergreen rhododendron that blooms in early spring with compact trusses of lavender to rosy-purple flowers. The small, dark green leaves are neatly shaped and often turn burgundy to mahogany in fall and winter, giving the plant year-round color and structure.
This classic hybrid originated at Weston Nurseries in Massachusetts in the late 1930's to early 1940's. It arose from breeding between Rhododendron carolinianum and Rhododendron dauricum var. sempervirens, resulting in a hardy garden rhododendron valued for dependable spring flowering and winter foliage color.

Design tip
Arrange ‘PJM’ near later-blooming shrubs so its early flowers open the season without competing for attention. As spring advances, allow neighboring plants to take over, creating a succession of focal points rather than concentrating the display into one period alone.
