This is the first report of Commelina benghalensis (Benghal dayflower, tropical spiderwort) in Virginia. Three mature plants with intertwined stems bearing numerous chasmogamous and cleistogamous flowers were discovered as weeds in a landscape planting of hybrid Hemerocallis, hybrid Iris, and a dwarf cultivar of Nandina domestica; nine nonreproductive seedlings were found about one meter distant in the same flower bed.
