And, since azaleas are such an important plant, arguably the keystone of the southern landscape, it seems only fitting to spend some time learning about this plant and its unique cultural requirements. There are literally hundreds of azalea varieties available from Georgia nurseries. As is the case with a lot of popular plants, the constant stream of new varieties makes it nearly impossible to keep track of all the new releases. However, let me give a quick run-down on some of the azalea varieties that I am familiar with. Kurmes, Kaempferi and Gables are known for their cold tolerance, but their winter foliage may not be as outstanding as other varieties.
Rutherfords are some of the most heat and full-sun tolerant azaleas.
Southern Indicas aren't as cold hardy as other varieties, but they offer superb drought tolerance. Delaware Valley White is one of the most shade tolerant azaleas and Encores will bloom continuously throughout the summer. Regardless of which variety you are looking for, ask your retailer about locally grown plant material - we have some fantastic azalea growers in the Athens area who can always use our support. Azaleas are shallow rooted plants and are often among the first plants to wilt when rainfall is scarce. Mulching will help conserve soil moisture around azaleas, but during periods of limited rainfall most azaleas will still need water.
