Azalea : Rhododendron

Gardens of the deep South are famous for this Southern Indica or Sun Azalea, More cold-tolerant than other Southern Indicas.

These deciduous or evergreen shrubs come in dozens of varieties and bloom in a wide range of colors. A species of Rhododendron, with similar soil and water requirements, Azalea may flower earlier and are usually smaller. The free-blooming and long-lived plants are usually as broad as they are tall, and are good for shrub beds, as backgrounds to flower borders, along pathways or in open areas. Some types bear fragrant flowers, such as lemon-scented Alabama Azalea (R. Alabamense) and rose-scented Coast Azalea (R. Atlanticum). Plant in acid soil in filtered sunlight or light shade, although plants tolerate full sun in cool-summer areas. Use soil rich in organic matter, which retains water and drains quickly. Plant in fall or spring with the top of the root ball slightly above the soil level. Water immediately after planting and spread a generous layer of mulch. Fertilize after flowering ends but before July 4. Never prune after mid-summer because those branches produce the next season's flowers. Never cultivate the surface soil near Azaleas.
