DESCRIPTION:
Creeping woodsorrel is a perennial that has alternate, compound leaves, each consisting of three heart-shaped leaflets resembling clover. Attractive yellow flowers, borne singly or in small groups, are very characteristic. The mature plant has creeping stems emerging from a slender taproot. The stems root at the nodes and invade larger areas. When seeds mature, pods open explosively, often spreading seeds 10 feet (300 cm) or more. Oxalis prefers shady situations. Creeping woodsorrel resembles buttercup oxalis, but the flowers are not as large and showy and the growth is less upright.

See UC IPM's Creeping Woodsorrel and Bermuda Buttercup Pest Note for more information.
