The National Wildlife Federation has designed a Native Plant Finder website to help you find the best native plants specifically for your area that attract butterflies and moths and the birds that feed on their caterpillars. This website is based on the scientific research of Dr. Douglas Tallamy, author of Bringing Nature Home: How You Can Sustain Wildlife with Native Plants and Nature’s Best Hope.

You can also join his efforts by visiting the Homegrown National Park website and putting your site on his map. Plus there is a ton of great info available on the site.
