On-line plant databases everyone can use
Here are some easy to use, free sources of information about native plants. Check them out for plant ID as well as where to find them and tips for growing them.
"The PLANTS Database." http://plants.usda.gov/. The US Department of Agriculture and other partners have collaborated on this great source for the vascular plants, mosses, liverworts, hornworts and lichens of the US and its territories. You can search by common or scientific name, as well as by taxonomy, growth habit, morphology, physiology, growth requirements, reproductive characteristics and use, and by location down to county level. There is a photograph of each species. Keys are available free in both on-line and download versions.
"Prairie Restoration: A Digital Aid Featuring Seeds, Seedlings, and Fruits." https://castle.eiu.edu/prairie/. Janice Coons. Nancy Coutant, Ken Robertson and Brent Todd of the Eastern Illinois University Department of Biological Sciences are the project leaders for development of this database funded by the Illinois Department of Natural Resources. Illinois tallgrass prairie species are described at all stages of development. There are species lists by common and scientific name, and a glossery.
"Landscaping and Restoration Using Illinois Native Plant Species." https://castle.eiu.edu/n_plants/. Also developed by Janice Coons and Nancy Coutant, this database describes the uses of native plants, the characteristics of individual plants, and tips on growing them.
