Kidney-weed dichondra is a low-growing perennial plant sometimes used as a ground cover, but which can also become weedy in some lawns. It is a localized weed throughout California.
Kidney-weed dichondra is easy to recognize by its small, kidney-shaped to almost circular leaves with rounded basal lobes and its creeping, dense matlike growth habit. Leaves are 1/4 to 1-1/2 inches (0.6–3.7 cm) wide, and are alternate to one another along the trailing stem. Leaves often form a shallow cup shape and are stalked.
Flowers are inconspicuous.
Kidney-weed dichondra spreads by seeds and aboveground, horizontal, creeping stems (stolons).
