Cinquefoil

Cinquefoil can be identified by its tough, wiry stoloniferous stems. The stems of this broadleaf weed elongate and then arch to the ground and root at the tips. Cinquefoil also has glossy, dark-green blades on the upper surface that are hairy to (sometimes) white and woolly underneath. Cinquefoil produces attractive yellow flowers with five petals, and these plants are often sold in nurseries. Several species can be found in home lawns.
