Wildflowers of the United States

Reference List for Tennessee Wildflower Identification
Site	Description
Tennessee Native Plant Society	Excerpt from their website: "The Tennessee Native Plant Society was founded in the spring of 1978 as a botanical organization for persons interested in the native flora of Tennessee. Members include wildflower enthusiasts from all over the state who share common interests in the areas of plant identification and folklore, growing native plants from seeds and cuttings for use in naturalized landscapes, and preserving natural areas to protect plants... Our members meet frequently at various locations all over the state for field trips..."
The University of Tennessee Vascular Plant Herbarium	Hosts nearly 7000 photos and distribution maps of Tennessee plants. You need to have a common or scientific name - at least to the genus - to effectively use the database. The photos by genus, as well as the county distribution maps are particularly useful.
Tennessee Pest Plants List (2009)	This is the latest list of Tennessee noxious weeds that I could find, which was apparently last revised in April, 2009. The plants on the list are considered "pest plants" and are not to be propagated, sold, or released within the state. There are 12 plants on the list as of April, 2009.
Kris Light's Website of East Tennessee Wildflowers and Hiking Trails	This site has as of this writing 715 different East Tennessee wildflowers in the various photo galleries, which can be searched by common name and scientific name. In addition, Kris Light has made wildflower photo/ID trips to Alaska, Arizona, California, Florida, Massachusetts, New Mexico, Texas, and Utah, and has additional wildflower photos from those states
Blueshoe Nashville Guide to Tennessee Wildflowers	Very nice photographs with common name, scientific name, and photograph location. Organized by location, but the small thumbnails on the main wildflower page can be used to scan for matches. Edited by Cheryl Hiers.
2bnTheWild.com	Daniel Reed's excellent 2bnthewild Site has photographs, identification information, and other interesting information about wildflowers (and other wildlife subjects) from the Southeastern United States. Since "Southeastern United States" isn't defined I've chosen my own list of states from the perspective that Daniel appears to be located near Memphis.
Southeastern Flora	Some very nice esthetically-pleasing identification photographs of a large number of wildflowers. Search criteria includes flower color, plant form (tree/shrub/herb/vine), leaf type, leaf arrangement, and species/common/family name. Note: If you don't know the entire name, use "%" at the end as a wild-card in the search. From the site: "...Currently there are over 1020 species listed on this site and over 14,400 pictures to help you identify what you're looking for..." This is an increase of 90 species in the 2 months between 8/15/09 and 10/15/09.
All Taxa Biodiversity Inventory	Comprehensive list of species inhabiting the Great Smoky Mountains National Park. I use it to confirm if an identified species exists in the park, since basically you need to know the taxonomy of the plant to find it in the data. In some cases, as is expected with classification in the state of flux we find it today, some of the scientific names DLIA uses are not accepted according to ITIS, and some plants are listed in families different from how I have them listed.
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.
Flicker Wildflower Field Guide, North America	Over 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.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: Wildflowers of Tennessee, the Ohio Valley and the Southern Appalachians: 2nd Edition (Commission to USWildflowers.com if purchased)	A product of the Tennessee Native Plant Society, this excellent and comprehensive field guide covers over 1250 species using 800 photographs and valuable descriptive text. While the focus is Tennessee, it's area of coverage includes the entire states of Kentucky and West Virginia, as well as large parts of 13 other states. In addition to the description of the plants it has an interesting look at botany from a historical perspective of the region. While the main part of the book is organized by plant family, there is a color-keyed section of thumbnails that allows a quick scan for identification, and there are illustrated keys for 12 of the families. This is my favorite wildflower identification book that I have, and I consider it a "must have" for wildflower enthusiasts in the region.
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.
