There are over 25 plumleaf azaleas throughout the Arboretum’s landscape. Together, they comprise an important conservation collection. The azaleas are threatened in their native habitats in Alabama and Georgia due to erosion after logging. In spring, the azalea grows dark green leaves. In late summer, when most plants are finished flowering, the azalea’s red and orange flowers emerge. The shrub’s dry seed capsules remain into the winter.
