Mid-West - From https://rodaleinstitute.org/blog/native-plants-found-in-the-us/
(Plantago major) grows in disturbed areas and is an easy edible and medicinal plant to identify. Plantain works as an antibiotic for cuts and is best eaten when the leaves are small in the spring. As the growing season progresses the leaves become bitter and the noticeable “veins” on the plant’s leaves become stringy. Common Yarrow (Achillea millefolium L.) is found in yards and fields. The leaves can be used as a coagulant, and the flowers and leaves in teas as a diuretic. For stopping the flow of blood, yarrow can also be useful by crushing up the leaves and placing them over the cut. Several types of “prickly lettuce” can also be found in the wild of the Mid-west. Examples include chickweed, mallow, dandelion, shepherd’s purse, nettle and sow thistle. Siberian elm, a common street tree in the Midwest, can produce thousands of pounds of delicious small green seeds, called samaras, which must be eaten before their edges start turning brown.
