Tradescantia, commonly called spiderworts, is a genus of about 65 species of herbaceous perennials from North, Central and South America. They are grown for their showy, three-petaled flowers and attractive foliage. The Andersoniana Group of hybrid spiderworts are some of the most common perennial spiderworts seen in cultivation. They are hybrids of various species including T. virginiana, T. subaspera and T. ohiensis. Cultivars in this group are sometimes given the hybrid name designation Tradescantia × andersoniana.
