| Benghal dayflower, or tropical spiderwort, is an annual or perennial, creeping herb that is on the Federal Noxious Weed List. Leaves are alternate, lily-like, 1.2-2.8 in. (3-7 cm) long and often have reddish hairs towards the tip. Aboveground flowers are very small with relatively large lilac to blue petals and are present from the spring into the fall. Underground flowers, which grow on burrowing rhizomes, are white and very small. Benghal dayflower invades areas with moist soil including roadsides, grasslands and other disturbed areas. It is especially problematic in pastures and crop fields where it forms dense, pure stands that can smother other plants such as low-growing crops. Benghal dayflower is native to Asia and Africa and was first found in the United States in 1963. |
