Description


Virginia buttonweed is a prostrate-growing perennial with branching hairy stems. The leaves are elongated, lance-shaped and grow opposite one another on the stems and are joined by a membrane. Virginia buttonweed prefers moist, wet conditions. The tubular flowers of Virginia buttonweed are white to purplish, and grow in the leaf axis along the stem. Flowers resemble four-pointed stars. Virginia buttonweed spreads by seed and plant segments. Virginia buttonweed is found throughout the Southeastern United States, and as far west as Texas.

Cultural Practices

Since the Virginia buttonweed plant prefers moist wet conditions, avoid excessive irrigation. If physical removal is attempted, take care to dispose of all plant fragments as Virginia buttonweed can reproduce from small pieces of the stems or roots.




Herbicide Use

Because of the plant's ability to reproduce from stem and root fragments, an herbicide application may be required to eliminate Virginia buttonweed from your turf site. Select a post-emergence broadleaf herbicide. For optimum control, applications should be made when Virginia buttonweed is in the 2-leaf to flower stage of growth.
