The Lady Bird Johnson Wildflower Center at the University of Texas has a really great website that helps you find recommended species of native plants for your area. You select your state and then you can narrow your search by adding your light requirements, soil moisture and the types of plants you want (shrubs, trees, annuals, etc.) You can even select bloom times and colors. They even have a suppliers directory so you can find plant nurseries in your area. The Gowanus Nursery is located near me in Brooklyn and also has a nice searchable database. You can even look up native edibles!!
