Virginia buttonweed is a prostrate-growing perennial with branching hairy stems. It often has a yellowish mottling due to the presence of a virus that grows in close association with this weed. The leaves are elongated, lance-shaped and grow opposite one another on the stems, joined by a membrane. Virginia buttonweed prefers moist, wet conditions and can tolerate close mowing. The tubular flowers 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.
