#3: Jack-in-the-pulpit (Arisaema triphyllum)
says, "Does poorly in heavy clay soil. Needs constantly moist soil that is rich in organic matter."
added, "A fairly common wildflower in Illinois found in moist woods settings flowering in April and May.
Flowers wrapped in a tube-like green sheath termed a spathe, folds over the flower top. Inside the spathe, flowers are crowded together along lower end of spadix (cylindrical brown or green column).
Cluster of shiny orange-red fruit evident in the fall.
Indians used the corm to treat sore eyes (Chippewas). Pawnee Indians used a powder prepared from corm and applied it to the head or temples to relieve headache. Corm also utilized in the treatment of snakebite, ringworm, gas, rheumatism, and asthma. Indians also used the corm, after boiling or baking (thereby neutralizing the unpleasant reactivity of the calcium oxalate crystals) for food."
