Azaleas considered to be evergreen or semi-evergreen grow two sets of leaves. Their spring leaves are thinner, larger, and grow along the stems. In the fall these leaves will be discarded. Summer leaves of this shrub are thicker, smaller, and are clustered near the branch ends. These leaves remain through winter, and depending on the variety, persist for several years.
Good drainage is important since they dislike wet feet. Blooms on old wood, so prune to shape immediately after flowering. Fertilize in early spring. Pine needle mulch is beneficial.
