OMG! I just realized that when I originally posted honeyvine, I clicked the wrong upload. So here's a do-over with the correct image. Honeyvine is a close relative of milkweed. This native makes a good garden addition to attract monarch butterflies and feed their caterpilars. It is of course a little toxic for the rest of us that don't have the ability to segregate those toxins so the birds don't eat us. Honeyvine grows in AL, AR, DE, FL, GA, IA, ID, IL, IN, KS, KY, LA, MD, MO, MS, NC, NE, NY, OH, OK, PA, SC, TN, TX, VA, WV, and ON. Cedar Bog Nature Preserve, Champaign Co OH, 8/19/11.
