|The PJM group of rhododendrons are smaller, growing to a height of 3 to 6 feet tall. Form is rounded and foliage is dark green until fall when it turns almost purplish. Produces trusses of 4 to 9 small, funnel-shaped, bright lavender-pink flowers. April flower color and size varies between cultivars, but is always vivid and showy.
One of the reasons the PJM group is such a heavy flowerer is that the plant does not set seed. An excellent rhododendron for the New England states.
PJM rhododendrons are the result of crosses between R. carolinianum and R. dauricum var. sempervirens. They were first developed by the Weston Nurseries in Hopkinton, Massachusetts.
