Wildflowers of the United States

Reference List for Nebraska Wildflower Identification
Site	Description
Nebraska Native Plant Society	"The mission of the Nebraska Native Plant Society is to promote the appreciation and conservation of Nebraska's native flora and to foster education and research on Nebraska's native plants." It's good to know there is a Nebraska Native Plant Society, but it's difficult to tell how active it is from the website.
Fontenelle Forest NatureSearch - Wildflowers	From 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.
Lady Bird Johnson Wildflower Center at the University of Texas at Austin	Perhaps the most comprehensive native wildflower information site in the United States. "Discover more than 10,050 plants native to North America."
USDA Plants Database	Great 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.
WildflowerSearch.com	Steven 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.
Item at Amazon: Field Guide to Wildflowers of Nebraska and the Great Plains by Jon Farrar (Commission to USWildflowers.com if purchased)	Arranged by flower color, which makes it easier to find if you don't know the family. The reviewers of this book seemed particularly impressed by the photographs. The descriptions of the plants are apparently not in-depth, but have the key characteristices needed for identification, which is exactly what you want for a field guide.
Wildflower Information.org	From 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.
Item at Amazon: National Audubon Society Field Guide to North American Wildflowers--E: Eastern Region - Revised Edition (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.
