Virginia Spiderwort

Virginia Spiderwort is a graceful perennial with grass-like foliage and three-petalled flower clusters in blue to purple. Each individual bloom lasts only a day, but new buds open continuously from June to September. The plant forms a dense clump and suits borders as well as naturalistic gardens.
