USDA Plants database
"Plant List of Accepted Nomenclature, Taxonomy, and Symbols. The USDA PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories." This is a nationwide native plant database that can be searched by State or by plant name. Each plant entry has photographs, maps to the county level showing native region, folklore and historical use, if known. Entries for wetland plants, rare and endangered plants, and common weeds are also listed.
Krista's recommendations
I receive multiple emails asking how to get started to create a native plant garden. I customized a reply to each question, but found that providing a comprehensive guide with plenty of resources would be helpful to people who want to take in as much good information as they can find before getting started with a plant list and a shovel. Here is a link to my best advice.
