We've now found an extreme way of dealing with all those white flowered plants that look so much alike in the parsley family. Put one in a different family! The genetic analysis of this plant resulted in a move from its historical classification to a different family, the ginsengs. To see this one, you either go into wetlands, or go south. This plant of water and sandy shores and marshes in the north often shows up in seasonally drier open areas in the south - even lawns. It can be found in AL, AR, CA, CT(E), DE, FL, GA, IN, LA, MA, MD, MI, MN, MS, NC, NJ, NY, OH(E), OK, OR, PA(X), RI, SC, TN, TX, VA, and NS. It's also found south into South America, and has now been introduced into most other continents. Collier Co FL, 1/25/13.
