The Southeast Exotic Pest Plant Council (www.se-eppc.org) strives to keep kudzu and other exotic plants from crowding out our native plants. The best way to help with this is to plant more natives and encourage them to grow. For example, the Landscaping with Natives Plants list for Tennessee, www.se-eppc.org/TN/landscape/landscape.html, features lots of great native plants to grow in our region.
If you're a woods wanderer-gardener like me, you'll love the book that I go to when I want to learn how to handle pretty native flowers. Growing and Propagating Wild Flowers, by Harry R. Phillips (University of North Carolina Press, 1985; $18), is a great book for learning how to identify and grow the wildflowers that you see decorating our woods.
