Ohio Spiderwort (Tradescantia ohiensis) perhaps the rare white 5/19/12 D&M MD

Found this one in the woods
-the pedicels are hairless
-no matter the petal color, the stamen hairs are always blue. There have been records of red flowers
-Caveat: hybridizes and hybrids with T. virginiana may or may not have hairy pedicels
