This water-hemlock bears bulbs. Actually more like bulbils, in the axils of the upper leaves. They're only about an eight of an inch long. The plant reproduces both by seed and with those bulbils. This water-hemlock is extremely poisonous. A piece of root the size of a walnut will kill a cow. This gets the hemlock name not from any resemblance to the tree, but rather the related plant that was used to execute Socrates. Bulb-bearing water-hemlock grows in or very near water in AK, CT, DE, FL, IA, ID, IL, IN, KS, KY, MD(E), ME, MI, MN, MT, NC, ND, NE, NH, NJ, NY, OH, OR, PA, RI, SD, VA, VT, WA(S), WI, WV, WY, and through Canada. Lenawee Co MI, 8/11/11. Celery family, Apiaceae.
