'White Angel' is a semi-evergreen shrub with an upright habit and bears an abundance of showy, white flowers, which open from lavender buds, beginning in mid-April. The 'P.J.M.' group of rhododendrons are smaller, growing to a height of 3 to 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 R. carolinianum var. album and R. dauricum var. album. It was first developed by the Weston Nurseries in Hopkinton, Massachusetts.
