DESCRIPTION:
Creeping woodsorrel is a perennial broadleaf plant with leaves resembling clover. They are fully subdivided, each consisting of three heart-shaped leaflets and alternate along the stem. The cotyledons (seed leaves) are oval to egg-shaped and hairless, except for minute hairs along the margins. 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 joints 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.
