About Rhododendron ‘Olga Mezitt”: ‘Olga Mezitt’ is a vigorous grower with a spreading, upright habit and bears an abundance of showy, vivid, peach-pink flowers beginning in late April. The ‘P.J.M.’ group of rhododendrons are smaller, growing to a height of 4 feet tall. Form is rounded and foliage is leathery and dark green until fall when it turns red, persisting through winter. 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. mucronulatum and R. minusm var. compacta. Zones 4 to 8.
