|'Weston's Pink Diamond' is a semi-evergreen shrub with a spreading, upright habit and bears an abundance of frilled, double, vivid, pink flowers in early April. The 'P.J.M.' group of rhododendrons are smaller, growing to a height of 6 feet tall. Form is rounded and foliage is leathery and dark green until fall when it turns almost purplish. One of the reasons the 'P.J.M.' group is such a heavy flowerer is that the plant does not set seed. An excellent rhododendron for the New England states.
This rhododendron is the result of a cross between another 'P.J.M.' hybrid and R. mucronulatum 'Cornell Pink'. It was first developed by the Weston Nurseries in Hopkinton, Massachusetts.
