Reference List for Iowa Wildflower Identification

Site Description
Iowa Native Plant SocietyThe Iowa Native Plant Society is a forum for plant enthusiasts, gardeners, and professional botanists to exchange ideas and information, and to work together to:
  • encourage conservation and ethical use of Iowa's plants
  • promote education about Iowa's plants, their habitats and cultural habits, and the preservation of these plants and their environment
  • appreciate and enjoy Iowa's native flora
Iowa Plants - The Iowa Living Roadway Trust FundFrom the site: "This plant database is designed to help you identify what plant species are native to Iowa... The database also serves as a learning tool by providing descriptive information about individual plants."

This is an excellent site from the Iowa DOT with a database of several hundred flowering plants native to Iowa. There are a number of search criteria, including name, bloom color, bloom month, and more.
Fontenelle Forest NatureSearch - WildflowersFrom the site: "We've identified close to 300 species of wildflowers so far by walking the trails and prairies of Fontenelle Forest and Neale Woods... To help in searching for a particular species page, the wildflowers are separated by color, and within each color category by the approximate date they first bloom. But be aware that intermediate or variable colors do occur..." Recommended by Rachel Hall, this appears to be an excellent site for wildflower identification for Nebraska, especially the eastern part of the state, along with the nearby states of SD, IA, KS, and MO.
Reny's WildflowersReny Parker's wildflower galleries, with "over 1,820 images identified to 79 plant families." Includes family and species common and scientific names, photo location. Searchable by color, shape, location, and name. Very nice photographs.
Lady Bird Johnson Wildflower Center at the University of Texas at AustinPremier native wildflower information site in the United States. "Native Plant Database - Search 7,024 native plant records by traits or names. Image Gallery - Browse through our collection of 23,770 native plant images. Ask Mr. Smarty Plants - Have a question? Mr. Smarty Plants has 3,584 answers. How To Articles - Don't know where to start, try one of our articles."
USDA Plants DatabaseGreat resource for native plants! Their own description: "The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories." Provides these important (to me) pieces of info: 1) Listing by state and county within a state where specific species have been identified. 2) Scientific name synonyms are listed. 3) Scientific names are matched to a widely-used common name. 4) Photographs of many species. 5) State by state list of all the species identified in that state. Official Citation: USDA, NRCS. 2009. The PLANTS Database (http://plants.usda.gov, 22 June 2009). National Plant Data Center, Baton Rouge, LA 70874-4490 USA.
Flicker Wildflower Field Guide, North AmericaOver 9,000 Flickr member photos tagged with wfgna. The WFGNA group has good tagging requirements for their excellent photos, so you'll find, in addtion to the photo, the state in which the photo was taken, and at least a common name and the scientific name as identified by the contributor. After you get to the linked page you should add search criteria, including the state name, the color of the plant, or scientific name, to reduce the number of photos. Several states have several hundred photos(California has over 1,500!) so you'll probably want to add color to the search criteria.
WildflowerSearch.comSteven K. Sullivan has done a tremendous job of putting together a database and search engine to help in identifying wild plants. Not only can you search by plant scientific and common names, you can narrow the results using location (currently lower 48 states and parts of Canada and Mexico), flower shape, color, size, habitat, and observation time. His database currently includes over 7,000 plants. Definitely worth checking out.
Wildflower Information.orgFrom the site: "WildflowerInformation.org is a resource for wildflower enthusiasts and gardeners. With a growing interest in the environment and natural gardening, our objective is to offer comprehensive information that is easy to use, and accessible for those from the casually interested to the expert."

While this information doesn't appear to be on the website itself, WildflowerInformation.org seems to be owned by American Meadows, the "recommended wildflowers seed supplier" of WildflowerInformation.org.

(Commission to USWildflowers.com if purchased)
"...gives full descriptions of more than 650 species found east of the Rocky Mountains, along with notes on several hundred more. The eminently sensible organization relies on first-impression visible characteristics..."
I use this guide frequently, and unless I have a good idea what family a flower is in, this is usually still my first stop. In my opinion, a must-have for beginning wildflower enthusiasts; augments more locale-specific wildflower references.
