    Found in prairie habitats.
    Of the 18 milkweeds known to occur in Illinois (the Prairie State), this one has the largest flowers.
    Thick stemmed, w/ milky sap.
  • Posted by SongofJoy (Clarksville, TN - Zone 6b) on Dec 13, 2012 10:27 AM concerning plant:
    This plant is used by Monarchs, Queens, and Soldiers as a caterpillar food source. It is very important to Monarchs as they move northward from Mexico through Texas. A few other caterpillars use the milkweed as food, but the nectar is relished by many butterflies including Swallowtails, Whites, Checkerspots, as well as a number of others.
