The most common Speedwell is a creeping, broadleaf perennial often grown as an ornamental. It frequently escapes planting beds and becomes weedy, especially in lawns. Speedwell has oval, green leaves that form a solid, spreading mat, which choke out desirable plants. Small white, blue or lavender flowers bloom in heart-shaped pods from spring into summer. If left untended, Speedwell can spread across an entire lawn within a few years.


Speedwell prefers acidic soil and moist, shady areas and is most troublesome in the Northern United States.
