The Biota of North America Program maintains a searchable database of vascular flora. It is searchable by family, genera or species. Geographic search terms are available and detailed down to county and zip code.
The Lady Bird Johnson Wildflower Center maintains a Native Plants Database for North America that includes more than 25000 species. Search options include habit, lifespan, light requirements, soul moisture, and bloom and leaf characteristics. Geographic search is at the state level.
Has extensive descriptions of plants and advanced search features including wildlife attraction, maintenance level, uses and other features. Geographic search is by zone and native information is available only for Missouri.
The USDA's Plant List of Attributes, Names, Taxonomy and Symbols provides information about the vascular plants, mosses, liverworts, hornworts and lichens of the United States.
This is a work in progress, but already has robust search and filter features. Geographic search features are at the state or regional level. There is partial information on invasive and noxious species as well as native plants.
