Tradescantia

Garden hybrids that are believed to represent Tradescantia ohiensis crossing with   T. subaspera Ker-Gawl. ×T. virginiana have been collected in MA (Sorrie and Somers 1999).  This plant has been called T. ×‌andersoniana W. Ludwig & Rohweder. However, the name  is invalid (Faden 2000). Further, the name has been used as a catchall for several different cultivated taxa (i.e., it does not represent a single, genetic entity).
