Thumbnails organized by blooming season or by color, you can also search the descriptive text to find the detail pages for each species. Scientific and common names are included.
    Minnesota WildflowersMinnesota Wildflowers has grown from Katy Chayka's original nice little site with 'information about wildflowers that grow in Minnesota, mostly those found in and around the Twin Cities area.' Katy incorporated the site as a non-profit and joined forces with others, allowing them to receive large, multi-year grants from the State of Minnesota as well as public donations. This enabled them to work full-time photographing wildflowers and building the site, going from 15 species in 2007 to over 1,400 ten years later. Minnesota Wildflowers has become a premier resource for wildflower information of the region.
    Missouri flora web page"Photographs and descriptions of the flowering and non-flowering plants of Missouri, USA." Organized by flower color and leaf structure (opposite/alternate.) Excellent plant detail pages. Published by Dan Tenaglia, who is now deceased, this is a great site for wildflower identification.

    The Noble Foundation Plant Image GalleryThe Samuel Roberts Noble Foundation's plant photographs of a large number of Oklahoma plants. Divided into three sections, the "grasses" and "trees/shrubs" group have the best search capabilities, with the forbs (herbaceous flowering plants) group having the weakest search engine, but they promise that to be improved.
    Alabama Plants"Photographs and information for the plants of Alabama..." This is another site by Dan Tenaglia, the now-deceased creator of the excellent and widely-used MissouriPlants.com website. It has over 300 wildflowers included in the approximately 350 plants presented on the site. The excellent thumbnail photos of the flowers are presented by color/leaf arrangement for easier identification. If you've used Missouri Plants, you know the excellent identification information Dan included for each species.
    Flora of North Dakota: ChecklistThis appears to be a true flora - all the plants of a region, although with under 2,000 species, I may be incorrect in that assumption. This is not designed as an easy identification guide, although there are photographs associated with many species. However, the location information (county list) and the ability to sort the list in different orders, and especially the exhaustive nature of the data will make this an extremely valuable asset in identifying wildflowers of North Dakota. Additionally, there is a PDF version available for download (LARGE), which makes scanning through the photos much easier. Alexey B. Shipunov is to be commended for this significant work, although he attributes the checklist as a collaborative effort of many people.
    Florida's Native Wildflowers - The Florida Wildflower Foundation"The Florida Wildflower Foundation is a 501(c)3 nonprofit organization whose mission is to enrich lives with Florida's native wildflowers... the Foundation funds research, education and planting projects statewide."

    Oregon Flora Image Project Excellent identification photographs of the flora of Oregon, by Dr. Gerald (Gerry) Carr, who is associated with the Department of Botany and Plant Pathology at Oregon State University. You'll need to know the scientific name of the plant you seek.
    Oregon Flora ProjectFrom the website: "The mission of the Oregon Flora Project is to serve as a comprehensive resource for the vascular plants of Oregon that grow without cultivation, and to foster effective use of this knowledge by all citizens."

    Flora of Oregon is a project of Oregon State University. The entire Flora of Oregon is scheduled for publication in 2015. When completed the website will contains information on all of Oregon's 4,560 vascular plants, as of May, 2014, 21 plant families have been published. The website also includes a plant atlas, photo gallery for identification, a rare plant guide with searchable database, a vascular plant checklist, and the semiannual Oregon Flora Newsletter. They also have a mobile app available for purchase from a link on their website, or from Amazon.com - linked below.

    Overall this is an EXCELLENT resource for wildflower and other plant enthusiasts of Oregon.
    Smoky Mountains Wildflowers Facebook GroupIf you're on Facebook (who isn't?) and are interested in wildflowers found in the Great Smoky Mountains National Park, then you need to like this page. Be part of the community.
    The Natural Treasures of OhioThis site is subtitled "A.L. Gibson Nature Photography Website", and is a blog, but Mr. Gibson has categories which make finding an article referencing a particular plant relatively easy if you know the scientific or common name. And when you get there, you get much more than his excellent photos. Definitely a site to visit regularly!
    Birdmom's Wildflower IndexOver 300 species with Common Name, Scientific Name, and Family name. Thumbnails indexed by blossom color. From the site: "Almost all of the approximately 320 species on these pages were photographed in Park Sierra's 120 acres in the Sierra Nevada foothills of Coarsegold, California. A few were taken in Oak Creek, situated in the town of Coarsegold, about 400-600' higher in elevation. "
    Flora of Virginia App by High Country AppsThis is a must-have if you are serious about Virginia wildflower identification - or any other plant in the state. It was built as a partnership with the Flora of Virginia project, a massive flora of over 3,100 Virginia species (see link to the book on this page), authored by Ludwig, Weakley, and Townsend - about as authoritative as you can get.

    An extract from High Country's description: "The FLORA OF VIRGINIA app is a complete guide for learning about the plants of Virginia, whether a wildflower from a weedy roadside, a shrub from a coastal dune, or a tree from a deep Appalachian hollow. The app does not need an Internet connection to run, so you can use it no matter how remote your wanderings take you."

    It even contains the dichotomous keys from the book - but of course there are shortcoming to trying to use those. However, it also contains a "Graphic Key" which allows you to include color of the flower to help identify it.

    You can get the book for around $100, or the app for $19.99. I was given a copy of the app for review, but receive no other compensation; I just like this app!
    Montana Plant Life"This web site presents a wide variety of Montana wildflowers and other plants growing in the wilds of Montana. The flora of Montana is very varied and contains many species which range extends from the Pacific Northwest region as well as from the Great Plains. The site includes edible plants, medicinal plants as well as poisonous plants with sub-categories for edible roots, poisonous berries etc. Choices can also be made for displaying introduced vs. native plants and weeds."

    "Each presented species has its own page with pictures, a full description and, if applicable, information about edibility, medicinal and poisonous properties. The plant search engine from the title bar above can be used to search the entire plant identification database for any words or phrases, for example 'lily', 'arthritis', 'Lewisia', 'cancer' etc." Excellent information on the many species represented - gcw

    Online Virtual Flora of WisconsinThe Online Virtual Flora of Wisconsin, in its own words, is "a collaborative effort between the herbaria of the UW-Madison (WIS) and the UW-Steven's Point (UWSP), along with most of the other herbaria located in the state of Wisconsin. It contains information on each of the more than 2600 vascular plant species that occurs in Wisconsin, including photos, distribution maps, specimen records, and more." You can search by common or scientific name (at least full genus, or even full family.) If you select "checklists" from the top menu, you can get lists with thumbnails that can be used to scan for a match. An excellent resource recommended by Twila Logan.
    Oswego State University of New York (SUNY) Rice Creek Field Station Digital Illustrated Flora"This guide is designed to provide a pictoral reference to the plants of Rice Creek Field Station, a unit of the College of Liberal Arts and Sciences at the State University of New York College at Oswego."

    Nelson, now Professor Emeritus at Oswego SUNY, includes links to the New York Flora Atlas for each of the wild-growing plants so you can determine in which New York counties the plant may be found.
    Range Plants of Utah at Utah State University Cooperative ExtensionExcellent information both helpful in identification as well as general knowledge about Utah plants. Organization of plant records is not conducive to ID by color or other attribute, since they are indexed by scientific and common names, but if you have an idea what the plant is, this is an excellent resource to help in confirmation, or just to learn more about a plant. The plant listings are subdivided by 'Forbs/Herbaceous' and 'Shrubs and Trees.'
    Washington Rare Plant Care and Conservation Program - University of Washington Botanic Gardens"The Washington Rare Plant Care and Conservation Program is dedicated to conserving Washington's native rare plants through methods including ex situ conservation, rare plant monitoring, research, reintroduction, and education."

It provides excellent of Ferns and Horsetails; Conifers; Flowers; Hardwood Trees and Shrubs; Grasses and Grass-like Plants; and Lichens, Bryophytes, and Blue-green Algae of the 7,230 square mile Upper Klamath Basin in southern Oregon and northern California. This includes the famous Crater Lake National Park.

    The book includes a photograph and description of by my estimate nearly 500 plant species.
    Flowers of RainierAmateur photographer and hiker Donovan Tracy has created a wonderful website describing and showing with beautiful photographs many of the wildflowers that can be found on Mt. Rainier in Washington State. This is a must-see site for those that want to identify wildflowers they may see while hiking on this mountain in the Pacific Northwest. The site has been updated from the 2011 season with additional species, bring the total to 230 as of April, 2012.
    Mountain Plants of the Western CascadesTanya Harvey is a self-proclaimed amateur botanist and gardener who is also an artist. She has combined those skills well in this website, which she is using as a repository and expository of the work she has done botanizing in the Western Cascades of Oregon while she prepares a book on the same for publication.

    There are plant lists for various locations in the Western Cascades. These can be helpful in identification by knowing what plants can be found at these spots. The "Plants and Places" blog also provides excellent information and photos on the plants of the Western Cascades.
    Southwest Desert FloraGene Sturla, a retired Arizona Game and Fish Department Wildlife Biologist, has spent about 5 years developing this beautiful and informative site which features about 700 species of plants found in the desert areas of Arizona and, naturally, nearby states as well.

    Eastern Colorado WildflowersFrom the website: 'Eastern Colorado Wildflowers contains photographs and information for over 525 plant species growing east of the Continental Divide in Colorado. Species listed in Weber and Wittmann's Colorado Flora: Eastern Slope, 3rd Edition are included.'

    This site has excellent photographs and information on when and generally where you might find the plant in bloom. Species coverage is excellent, with over 525 species included as of June, 2010. The plants are organized by family, scientific name, and common name.
    Idaho Mountain Wildflowers528 species of wildflowers found in the mountains of Idaho, with many also found in surrounding states. They are listed by common name, scientific name, and by family. I'm not sure all of the reclassification which has been used by the authors has been widely accepted, but the information and photographs are excellent. This site is based on the book by the same name, which you can purchase from Amazon at the link below.
    Wild About Texas WildflowersAccording to the website, Lone Star Internet, Inc. developed the Wild About Texas Wildflowers site out of a love for the Texas outdoors, the responsibility of capable internet design firms to aid in providing content to the online community.

    They currently have over 120 wildflowers categorized by color and listed by common name.

    Site recommended by Divamover.
    Wild Florida Photo Florida Plant ListNature Photographer Paul Rebmann has photos and information about many of Florida's wild plants, most with several excellent photographs and additional information about the plant.
    Wildflowers Native to Maryland at Wildflower FarmWildflower Farm is a commercial wildflower seed company that seems pretty eco-friendly. This is a listing of the indigenous Maryland species (53 at this writing) for which they have seeds. They are ordered alphabetically by scientific name.
    William Britten Photography: Smoky Mountain WildflowersThis website of William Britten, a professional photographer based in Gatlinburg, TN, right on the edge of the Great Smoky Mountains National Park, has beautiful photos, descriptive information, and suggested locations for around 100 species of wildflowers found in the Smokies. William is also associated with the Facebook page mentioned above.
    Charles and Diane Peirce's Michigan Wildflowers*Very* nice photographs of 543 species (as of January 2015) of Michigan wildflowers sorted by common name and by scientific name. You must select a plant name to see the photos of that plant, so it is somewhat difficult to browse through the site to identify a plant unless you already have an idea of what it may be, but the photos are excellent - both beautiful and useful in finding identifying characteristics. The Peirce's report that after 16 years of effort, they have photographed all of Michigan's native orchids.
    Northwest Ohio Wildflowers at Ohio-Nature.comJon Cross has organized the galleries of his large collection of wildflower thumbnail photos by color for easier identification. These are further separated by native / non-native status. He also identifies rare and endangered species found in NW Ohio. In some cases Jon provides additional information about a flower, but in most cases you can get only a larger version of the image, and the common name of the plant.
    San Diego County Wildflowers - Identifying Them From the site, by Ken Bowles:

    "This guide is for people who
    1. Want to identify the many interesting wildflowers they see growing in wild places in San Diego County, and
    2. Lack formal botany education, and/or the needed experience, to rely on formal botanist publications, and
    3. Want to do as well as possible at identifying the Family, Genus, and Species using only visual information."
    Southeastern Arizona Wildflowers and Plants"Southeastern Arizona Wildflowers and Plants features photographs and descriptions of 449 different wildflower and plant species found here in the southeastern part of Arizona, USA. Featured are Sonoran Desert wildflowers and the plant species found in the areas surrounding the city of Tucson, Arizona in Pima County."
    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.
    Wildflowers of the Southern Rocky MountainsThis website provides beautiful photographs of over 1,000 species of plants (including grasses, sedges, and trees) found in the southern Rocky Mountains of the United States. The plants' primary presentation is by color and inflorescence shape, making it relatively easy for the beginner to find a flower, but other search options are also available.

    An excellent resource for those seeking to identify wildflowers of the southern Rockies.
    Zydeco Louisiana Iris Garden - The Species of Louisiana IrisZydeco Louisiana Iris Garden is the outgrowth of Patrick O'Connor's thirty year hobby growing and hybridizing Louisiana irises. In Patrick's own words "The site has extensive information on the five recognized Louisiana iris species, I. hexagona, I. fulva, I. giganticaerulea, I. brevicaulis, and I. nelsonii. Today, it is no longer thought that I. hexagona occurs in Louisiana (it is an East Coast and Florida species), but the other four are native to the state as well as elsewhere."

    Definitely worth a visit to help identify / understand Irises of Louisiana.
    Flora of Eastern Washington and Adjacent IdahoFrom the site: "This site is provided for instructional and educational purposes or for the enjoyment of all those who enjoy the beauty of nature.The majority of images are from taxa found at or near the border between Idaho and Washington. The ultimate goal is to provide images of all taxa found in the region from the base of the Cascade Mountains to western Idaho. However, the emphasis of this project will always be the region near the border between the two states." Site owned by Robert L. Carr and Gerald D. Carr.
    Gallery of Florida Wildflowers, Insects, and Other Creatures Excellent photographs and interesting brief essays on a number of wildflower species found in Florida by Michael E. Abrams.
    Hillside to the Hollow Coalition - WildflowersThe Hillside to the Hollow Coalition is a group working to preserve for trails and recreation a 300-acre open space area that is located where Boise meets the Boise Foothills.

    The wildflowers page of The Hillside to Hollow Coalition website shows a number of wildflowers that are found within this 300-acre area.
    Michigan Flora Online - University of Michigan HerbariumRecommended by Ron Gamble - Based on the website description: "The immediate goals of MICHIGAN FLORA ONLINE are to present, in a searchable and browsable form, the basic information about all vascular plants known to occur outside of cultivation in the state."

    From Ron Gamble: '...really nice Search function, lots of photos for many of the plants listed. - (best and most important advice: don't add too much information in the search line, e.g., just type first few letters of sci or common name...)

    'Example: Type "catch" in the Search menu in the "common name". All the catchflys will come up in a list. If you see an icon under the "image" column, there is at least one photo. Click on "sleepy catchfly", info specifics will appear, and below the image you'll see the link "all images". Click it and you'll see a number of photos.'

    My take: This is not exclusive to flowering plants, but appears to be an invaluable aid to identification of wildflower species found in Michigan. It is searchable by common and scientific names, family, genus, and some plant characteristics. It usually includes at least one photograph (frequently several) of the plant to help in identification, as well as listing the counties where it has been confirmed to have been found. It includes some descriptive information, although in my limited perusal of the site it appears to be more descriptive of the habitat, growth habit, and origin than of the plant itself. Still, a very valuable and admirable asset, and if I were identifying plants I found in Michigan, I would refer to this site in most cases as a confirmation or even as a primary identification source.
    Sonoran Desert Plants "Guide with color photos and line drawings to almost 400 species of Sonoran Desert Plants." This is the flora section of Arizonensis.org - a website focused on Arizona Natural History. The flora section presents nearly 400 plants of the Sonoran Desert in Arizona.
    University of Wyoming Rocky Mountain Herbarium"Founded in 1893 by Aven Nelson, the Rocky Mountain Herbarium (RM) contains the largest collection of Rocky Mountain plants and fungi in existence with additional representation of the floras of other parts of the Northern Hemisphere."
    Wildflowers of Augusta County, VaParaphrased description from the author, Dr. Eric Jones of the School of Science at Mary Baldwin College in Staunton, VA:

    The site is the result of a quarter century of teaching a field botany course, mainly to nonmajors, and a love of photography. This site is an attempt to introduce you to 240 of the wildflowers of Augusta Co. VA. All pictures taken in Augusta County VA, located at the Southern End of the Skyline Drive - Northern end of the Blue Ridge Parkway.
    Wildflowers of Texas"This site is dedicated to providing information and photos of all varieties wildflowers and plants that grow in Texas. I hope you will find this website informative and enjoyable."

    Alva Chance has published photos and information on over 100 Texas wildflowers, organized by blossom color. There are a number of very nice photographs useful for identification for each plant.
    DLiA - Discover Life in America, Division MagnoliophytaThe website description says "The mission of Discover Life in America is to discover and understand America's species through science and education for conservation." However, at this point it appears to be only focused on life in the Great Smoky Mountains National Park. I use it to provide a species listing of flowering plants in the Smokies. In some cases, as is expected with classification in the state of flux we find it today, some of the scientific names they use are not accepted according to ITIS, and some plants are listed in families different from how I have them listed.
    Georgia Exotic Pest Plant Council List of Non-native Invasive Plants in GeorgiaFrom the website: "The purpose of the Georgia EPPC Invasive Plant List is to identify and categorize plants that pose threats to natural areas in Georgia. Natural areas are those areas that are managed to conserve or restore the native plant communities. For this list, invasive plants do not include plants that are only problems in agricultural or pastoral systems. The list does not have regulatory authority; it is intended to aid in land management decisions and increase public awareness of invasive species."

    Minnesota Noxious Weed List (2017)Excerpted from document:
    The Minnesota Noxious Weed Law defines a noxious weed as an annual, biennial, or perennial plant that the Commissioner of Agriculture designates to be injurious to the public health, the environment, public roads, crops, livestock, or other property. The purpose of the law is to protect residents of the state from the injurious effects of noxious weeds.

    There are currently forty-one plant species regulated as noxious weeds in Minnesota.
    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 TrailsThis 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
    Wildflower SightingsWildflower Sightings is a beginning effort at a "Community" website where you can share your wildflower sighting, photographs, and information, and, of course, see what others have found. There is an opportunity for discussion and wildflower identification help from the community. This site looks like it has a lot of great potential as the community grows.

    Right now (March, 2013) the sightings listed are limited to Texas (plus one sighting from NE Georgia) - the location of the originators of the website, presumably - so I'll list this in Texas wildflower identification resources.
    Blueshoe Nashville Guide to Tennessee WildflowersVery 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.
    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.
    Idaho Wildflowers Mobile App by High Country Apps, LLC Extract from the publisher description: "The University of Washington Herbarium at the Burke Museum has partnered with the University of Idaho's Stillinger Herbarium, Idaho State University's Ray J. Davis Herbarium, Mark Turner, and High Country Apps to produce Idaho Wildflowers, a plant identification app for smart phones and tablets. The app provides images, species descriptions, range maps, bloom period, and technical descriptions for more than 800 common wildflowers, shrubs, and vines found in Idaho and adjacent areas of Washington, Oregon, Montana, and Utah. The majority of species included are native, but introduced species common to the region are covered as well. The app does not need an Internet connection to run, so you can use it no matter how remote your wanderings take you."

    I have purchased this application since it is available for the Kindle Fire HD, and I think it will be a great resource when I get back to Idaho. However, it is no longer listed on Amazon.com, so I assume that the Kindle version is no longer available.
    Oregon Wildflowers Mobile App by High Country Apps, LLC A description provided to me by Oregon State University: "The Oregon Flora Project at Oregon State University and High Country Apps have partnered to produce the new Oregon Wildflowers plant identification app for iOS and Android mobile devices. The app provides photographs, range maps, bloom period, and detailed descriptions for more than 940 common wildflowers, shrubs, and vines that occur throughout Oregon and adjacent areas of California, Washington and Idaho. Designed for both budding wildflower enthusiasts and experienced botanists, Oregon Wildflowers will appeal to individuals who are interested in the names and natural history of the plants they encounter. It is an excellent educational tool for all ages to learn about botany, plant communities, and ecology using the plants found throughout Oregon. Each of the 948 plants profiled has multiple photographs, distribution maps, and a detailed description. The majority of species included are native, and introduced species common to the region are also covered. Plant hunters can use the app to identify species in all ten of of Oregon's diverse ecoregions. Users can browse through the stunning photographs of plants organized by common name, scientific name, or by family to select a plant and access the related information. However, most users will likely use the identification key that is the core of the app to identify an unknown plant of interest."

    The application, which I'm sure has a large database and therefore requires a fair amount of memory on your device, does not require an Internet connection to use after the initial download. This application is no longer listed as working on Kindle Fire tablets. However, it does work on other Android devices, and reportedly on IOS (iPad / iPhone).
    Washington Wildflowers Mobile App by High Country Apps, LLC Modified publisher description: "The University of Washington Herbarium at the Burke Museum and High Country Apps have partnered to produce the Washington Wildflowers plant identification app for iOS and Android mobile devices. The app provides images, species descriptions, range maps, bloom period, and technical descriptions for 870 common wildflowers, shrubs, and vines found in Washington and adjacent areas of British Columbia, Idaho, and Oregon. Each of the 870 plants profiled has multiple photographs, distribution maps, and a detailed description. The majority of species included are native, and introduced species common to the region are also covered. Most users will likely use the identification key that is the core of the app to identify an unknown plant of interest.
    Flora by MaxPDF files containing information and photos about 147 different plant families, covering about 1,187 species and varieties. Generally there is a single PDF file for each family, although some of the families are so large Max has 2 or more PDF files to cover the family (Asteraceae has 10.)

    Max Brown has built an impressive botanical collection. He is an amateur botanist (a retired geologist) and so the information is presented using some pretty technical language, but if you know the family you're interested in, Max's site is worth the time for the visit.
    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.
    Hiking Trail Wildflowers and Plants by the OFHCAs of Aug 22, 2009, 325 species by the 30 members of the "Old Friends Hiking Club" taken as they hike the trails of northeast Georgia, southwest North Carolina, and northwest South Carolina. Flower lists are available sorted by common name, scientific name, or time of year the photo was taken. The thumbnail description also tells which trail on which the photo was taken.
    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.
    Southeastern FloraSome 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.
    Turner Photographics Wildflowers of the Pacific NorthwestOver 7,000 excellent photographs from Washington and Oregon and northern California, by one of the co-authors of 'Wildflowers of the Pacific Northwest' (see below.) These are indexed by Latin and Common name, by blossom color, and by blossom characteristic. Good information about each species, and the detail page includes a county-level map of distribution. This is one of my first go-to sites for wildflowers in the northwestern United States.
    Wildflowers WestMark Lee Dixon's & Darice Susan Dixon's wildflower website, with wildflowers organized by blossom color. They usually include multiple photographs of a plant, with at least one of the blossom and another of the whole plant or the leaf infrastructure to help with identification. Additional informative text is included, including common and scientific names. Very nice photographs.
    Wildflower Field Guide - DesertUSAOver 50 species of wildflowers found in USA deserts, organized by flower color. Common name, scientific name, and desert regions in which they are found - Mojave, Sonoran, Chihuahuan, and Great Basin. These deserts touch 7 states in the western US.

    This site also has good information about parks and destinations within these deserts, including, as an example, updates on wildflower status within the Anza-Borrego Desert State Park. Check on the "Destinations" drop-down menu at the top of the pages.
    All Taxa Biodiversity InventoryComprehensive 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.
    Flora of the Inland Pacific Northwest by Thayne TuasonOver 300 plants of Central Washington, and more from Idaho. Organized by scientific name, grouped alphabetically.
    Lady Bird Johnson Wildflower Center at the University of Texas at AustinPerhaps the most comprehensive native wildflower information site in the United States. "Discover more than 10,050 plants native to North America."
    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.
    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.

This book covers all of the known 3,164 plant species found in Virginia, including not only technical descriptions and keys, but illustrations for 1,400 of them. It is not a field guide, but a research reference to be held in great esteem.

    Described as "a no-nonsense wildflower reference and identification guide" and "sorting small-sized pictures of Wyoming wildflowers by color and flower shape, makes identifying a given species of flower an extremely simple task" by a reviewer on Amazon.com.
    Item at Amazon: Wildflowers of Arkansas
    (Commission to USWildflowers.com if purchased)
    Describes 600 wildflowers of Arkansas, with color photographs of 484 of them. Organized by family, which may make identification more difficult for the beginner than those organized by color and blossom shape. This book received very high reviews by purchasers, both for the quality of the photographs and for the plant descriptions. In my opinion, this would be an excellent companion to a field guide such as Audubon's.
    Item at Amazon: Florida Wild Flowers and Roadside Plants

    Wildflowers of Ohio by Robert L. Henn This second edition of the 1998 paperback by Robert L. Henn has an interesting format to assist in identifying wildflowers. It presents over 300 species of Ohio wildflowers, three to a page with descriptive information on each species on the opposite page. This looks like an excellent guide, and seems to be well-regarded. If I lived in Ohio I would own one.
    Item at Amazon: Idaho Mountain Wildflowers: A Photographic Compendium
    (Commission to USWildflowers.com if purchased)
    This is the third edition of Idaho Mountain Wildflowers. The second edition included over 500 species which are found in the mountains of Idaho, and the 3rd edition has added many more wildflowers. The information and photographs included are excellent. It is organized alphabetically by family, so it might take some browsing to find a wildflower unless you are experienced enough to recognize the family, but the family information itself is worth the price of entry.

    I own the 2nd edition, purchased for a trip to Idaho, and it has proven itself to be an excellent investment. Many of the flowers found in the Idaho mountains are also found in nearby states as well as in lower elevations, extending its usefulness. The main complaint I have is that some of the page numbers in the index are incorrect in the 2nd edition.
    Item at Amazon: Wild Orchids of Texas

    This appears to be a very nice photographic guide targeted for those of us who are not botanists. The author, Reny Parker, has been a president of a local chapter of the California Native Plant Society, so has established her credentials for knowledge and access to knowledgeable friends.

    Reny presents 358 species of wildflowers found in Marin, Sonoma, Napa, and Mendocino counties of California with brief, understandable descriptions and over 500 beautiful photographs.

    The author also maintains the Reny's Wildflowers website described above.
    Item at Amazon: A Guide to the Wildflowers of South Carolina
    (Commission to USWildflowers.com if purchased)
    A Guide to the Wildflowers of South Carolina by Richard D. Porcher and Douglas A. Rayner takes an interestingly different approach to grouping the more than 700 described species by habitat, while most other field guides group the photographs by color or by plant family. This is much more than a wildflower identification field guide, however, including information on the natural history of certain plant groups, itineraries for wildflower expeditions in South Carolina, essays on a variety of related topic, and more.

It takes over 1,000 pages to describe and illustrate the plants of Pennsylvania. This appears to be among the most respected technical manuals on Pennsylvania flora. Much of the identification process is likely by key attributes rather than by visual images. This will not be a guide you carry into the field with you
    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.

It received good reviews (4+stars) on Amazon.

    Item at Amazon: Wildflowers and Ferns of Indiana Forests: A Field Guide (Indiana Natural Science)
    (Commission to USWildflowers.com if purchased)
    From Amazon: "This beautifully illustrated guide identifies nearly 300 common plants in Indiana's most prominent ecosystem--the Eastern Deciduous Forest. For ease of identification, the plants are arranged by flower color or growth form, providing a convenient way to distinguish a great majority of plants in any given woodland. Generous treatment is given to all major vascular plant groups of the forest, such as wildflowers, ferns, shrubs, trees, grasses, and sedges. Michael A. Homoya not only helps with identification, but also offers information on a plant's habitat, flowering period, familial relationships, biology, and connections to Indiana. For the garden enthusiast and habitat restorer, there is a section on landscaping and natural community restoration using native forest plants. A portion of the proceeds from each sale of this book go to the Indiana Department of Natural Resources for land protection and stewardship."
    Item at Amazon: Photographing Smoky Mountain Wildflowers: (including Blue Ridge Parkway) (Photographing the Smokies) (Volume 3)
    (Commission to USWildflowers.com if purchased)
    Beautiful photographs of 200 species of wildflowers that are found in the Smoky Mountains, along with suggested trails and locations in the park where wildflowers can be found. Includes scientific name and common names, along with family common name, habitat type, and bloom period. In my limited review of the book, there appears to usually be a single photo per species and little descriptive information, so if there are similar species, it might be difficult to determine if the plant you are attempting to identify is actually the species in the book or instead one of the similar species. If, however, you want to generally identify the plant ("Bluet" for example, rather than "Creeping Bluet") it appears that this book can be a very good aid.
