Rhododendrons are ornamental, ericaceous, broad-leaved evergreens.
Azaleas belong to this genus, but many are not evergreen. They grow best in shade or partial shade. A south or southwest exposure increases the chance of winter injury to evergreen types. Plant in an acid, moist, well drained soil with a pH between 4.5 and 6.5. Several species of azalea and rhododendron are hardy in Michigan.
