Wildflowers of the United States

Reference List for Minnesota Wildflower Identification
Site	Description
Minnesota Native Plant Society	"A non-profit organization dedicated to the conservation and appreciation of Minnesota's native plants and plant communities through education and public awareness"
Minnesota Wildflowers	Minnesota 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.
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.
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: Northland Wildflowers: The Comprehensive Guide to the Minnesota Region, Revised Edition (Commission to USWildflowers.com if purchased)	"For more than two decades the first edition of Northland Wildflowers has been the standard guide to wildflowers of the Upper Midwest and Canada..." This is the revised edition, with updated photos and additional species.
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.
Item at Amazon: Wildflowers of Wisconsin and the Great Lakes Region: A Comprehensive Field Guide (Commission to USWildflowers.com if purchased)	"Describing more than 1,100 species, this is a comprehensive guide to wildflowers in Wisconsin and parts of Minnesota, Michigan, Illinois, Indiana, Iowa, and Ontario. A new introduction to this second edition discusses wildflowers in the context of their natural communities. Packed with detailed information, this field guide is compact enough to be handy for outdoors lovers of all kinds, from novice naturalists to professional botanists."
