Problem:

Speedwell

Veronica filiformis Speedwell, also called creeping Veronica, was originally used as a rock garden plant. Over the years it has become a weed, invading lawns and flower beds. This perennial plant reproduces by creeping stems that root easily at their nodes wherever they touch the soil. The seeds in the heart-shaped seedpods seldom mature, so the plant does not reproduce from seeds. Speedwell thrives in moist, shady areas but will grow in sunlight if the soil remains moist. This ground-hugging plant spreads quickly. In a few years, it can spread from a few patches to cover the entire lawn. It does not completely crowd out desirable grass, however. Speedwell does not invade areas that are well fertilized, are well drained, and get lots of sunlight.
