Scientific Name: Oxalis corniculata

Description

Creeping woodsorrel is similar to yellow woodsorrel (Oxalis Stricta), but is a creeping summer perennial. The leaves of creeping woodsorrel are deeply lobed, heart shaped, and may be green to reddish purple. Creeping woodsorrel contains a slender taproot, and roots at nodes along slightly hairy stems. The flowers of oxalis corniculata are yellow, contain 5 petals, and form in clusters of 1 - 5 at the end of slender stems. Creeping woodsorrel spreads by seeds. Creeping woodsorrel is found in eastern North America, to North Dakota and Colorado.

Cultural Practices

Creeping woodsorrel may be removed by hand when plants are young. Dense, vigorous cool-season turf areas will resist infestation. Follow good turf management practices including disease and insect control and proper fertilization.

Herbicide Use

For optimum control, make your post-emergence herbicide application to plants that are actively growing and in the seedling to flower stage of growth.
