Apocynum cannabinum. Also known as Indian Hemp because native Americans used the fibers for rope and nets.

Plant native to Lucas County grows 2 1/2 to 4 feet tall, generally in colonies, in sunny wet to mesic locations, including moist prairies and marsh margins. Reddish stems bleed white milky juice, bitter and toxic. Tiny white flowers appear late spring to midsummer in branching clusters at the tops of stem branches on short side stalks.

Prairie Dogbane is a very adaptable plant, tolerating spring flooding and fall droughts. Spreads aggressively from underground rhizomes in moist open areas; occasionally a "pioneer" in poorly drained disturbed areas.
