Finding the right plant for the right place can really be a chore! Fortunately, there are several excellent references that will help you find what you need.
Try these University of Georgia publications first:
Landscape Plants for Georgia
a great source of information on the size, form and habitat for trees, shrubs and ornamental grasses
If these don’t help, you may find what you need at the University of Georgia Extension Service Horticulture site:
Please note that some of the plants listed in the University of Georgia publications can be invasive. Purple loosestrife, Japanese pachysandra, periwinkle (common vinca vine), Asian wisteria, ligustrum, mimosa and English ivy can escape cultivation and wreak havoc on native plant communities. For a more comprehensive list of non-native invasive plants, visit the Georgia Exotic Pest Plant Council.
The Georgia Native Plant Society has a nice list of native plants, suppliers and garden designers. Native plants have much to offer your landscape, including drought tolerance, attraction to wildlife and the knowledge you are helping preserve threatened plants.
