Ask Mr. Smarty Plants

We believe you are referring to Apios americana (groundnut), which can be a little aggressive, but if it will work under trees in heavy shade, we'd say go for it. Anyway, we're certainly glad you're replacing your English ivy, as it is a non-native invasive.See this Plant Conservation Alliance Alien Plant Working Group Least Wanted website on Hedera helix (English ivy) for reasons why it is not a good choice. You are obviously already in favor of using native plants, but you might read our How-To Article A Guide to Native Plant Gardening to reinforce your ideas. 

Before we try to find some other satisfactory replacements for that ivy, lets address your problem of being unable to find natives or information on them in your area. Our Native Plant Database has thousands of plants native to North America and to specific states and Canadian provinces, and can be easily searched. You can use "Combination Search" to search on Georgia, and for the habit of plant you wish to have, including how much sun is available where you want to plant, and soil moisture. When we did a test run on this, selecting on Georgia, vine (habit) and shade, we got 13 possibilities, including the aforesaid groundnut, but some others we weren't too keen on, including Toxicodendron radicans (eastern poison ivy). So, we opted instead to try Recommended Species, used Narrow Your Search after clicking on Georgia on the map, and again searching for vines and shade. This time, we got three suggestions: Parthenocissus quinquefolia (Virginia creeper), Celastrus scandens (American bittersweet), and Wisteria frutescens (American wisteria). 

We used vines as an example so you could see how our Native Plant Database works, and find plants on your own. For instance, you could search on "Herbs" (herbaceous flowering plants) under Habit, selecting on shade and perhaps bloom color. You might not get any selections at all for that, or you might get several. Or try "Ferns" under Habit and see what that yields. Follow each plant link to the individual page on that plant and learn its preferences as to soil and moisture, whether it is deciduous or evergreen, how big it can be expected to grow, etc. 

Now, as to your complaint that the local nurseries have nothing but non-natives, you may not be visiting the right nurseries. The plants we recommend in our database are all commercially available. Go to our Native Plant Suppliers section, type in your town and state in the "Enter Search Location" box and you will get a list of native plant nurseries, seed suppliers and landscape and environment consultants in your general area. We can't provide you with a catalog of plants indigenous to Georgia, but we can come pretty close.
