The genus Veronica is responsible for a number of difficult to control turf weeds. Speedwell, which is the common name, refers to the swift way this family grows and spreads. Common speedwell is certainly not the most difficult weed problem in this family, nor the most common. It grows in various places througout the eastern half of the United States, except the deep South. Leaves are rounded, opposite each other and covered with hairs. It spreads by rooting at these leaf junctions and forms dense patches. Flowers are pale blue, marked by darker lines. Seed capsules have typical heart shape.
