Buttonweed
Diodia virginianaAlso known as Virginia Buttonweed, Common Buttonweed
Virginia buttonweed forms dense, creeping mats across damp lawns, ditches, and riverbanks throughout the southeastern United States. Small white, star-shaped flowers with four petals emerge directly from the leaf axils from spring until frost. Deep taproots and spreading fleshy stems allow it to thrive in soggy, poorly drained soils where other groundcover struggles.
