    Rhododendrons are shrubs with showy flowers in spring, usually in shade of white, pink, purple and red. Some types of rhododendrons that lose their leaves in winter are commonly called azaleas. Relatively few rhododendrons are fully hardy in the Chicago area or can cope well with its alkaline soils. The hybrid Rhododendron P.J.M. does very well in cold climates and is one of the hardier rhododendrons for the Chicago region. It is able to tolerate near-neutral soils.
