A tough perennial weed with pretty purple flowers that's notoriously hard to get rid of once established in a lawn.

Heart-shaped leaves with scalloped edges growing low in a rosette, topped by nodding blue-violet flowers in spring. Unlike ground ivy, it has no square stem and no minty smell. It spreads by rhizomes underground, which is why pulling it rarely gets rid of it for good.
