Tallgrass Prairie

From Fort Scott National Historic Site, National Park Service:

While walking on the Tallgrass Prairie you may find things to see other than the Bluestem grass and flowers. For instance you may find a wide variety of insects. One example is this Praying Mantis which was spotted by a Park Ranger while photographing flowers. The Praying Mantis, named for the position of the front legs, preys on other insects and the female will often eat their mates during or after mating is finished. Usually the recipient of their slow stalking is a fly, moth, or other smaller insect. While the Mantis may move slowly toward their prey their legs move so quick to grab their prey that they often cannot be seen by the naked eye.

Blue Sage

From Fort Scott National Historic Site, National Park Service:

Blue Sage grows wild on the prairie and is also called Pitcher Sage and its Latin name is Salvia Azurea. The name Pitcher Sage is to honor Dr. Zina Pitcher a US Army Surgeon and Botanist from 1822-1836. Blue Sage can grow to a height of 5 feet and blooms anywhere from July to October and grows everywhere in the state except the far western edges of Kansas. Blue Sage is a part of the mint family. Salvias are astringent plants that have been found to work well on nerves as a soothing agent. Meaning, mint tea, and possibly sage tea would have a calming effect. However, we do not recommend using Blue Sage for medicinal purposes without consulting a professional.

Fringe-Leaf Ruellia

From Fort Scott National Historic Site, National Park Service:

This small purple flower, called Fringe-Leaf Ruellia, is hard to find since it only opens for one day and then it will fall. It’s also small, reaching a height of only 4-20 inches. It grows in the eastern half of Kansas and is drought resistant; livestock also love to eat it. If you find this sweet little flower be careful because the petals will fall off if you shake it.

Walking Onions

From Fort Scott National Historic Site, National Park Service:

These are Walking Onions. The name of this herb/vegetable sounds like something from a cartoon, or a bad superhero name. They are also known as tree onions, top onions, winter onions, and perennial onions. This plant, which can be invasive, is called a walking onion because it will spread itself all over your garden, or the prairie, with no effort from you. The plant in the right climate with produce chives from the spring to the fall and the bulbs can be eaten as well. They have a strong flavor and don’t have to be peeled like many other onion varieties. 
(We recommend consulting an expert before eating any wild plants.)
