Creeping Oxalis, also commonly known as Creeping Woodsorrel, Oxalis and Sourgrass, is a creeping summer perennial weed that is frequently found in lawns and gardens. Oxalis corniculatais found in much of the continental United States.
Identifying Creeping Oxalis -
Creeping Oxalis (or Sourgrass) features many branches sprouting from a slender taproot. These branches form slightly hairy stems, which are green to purple in color and root at the nodes. Creeping Oxalis also features leaves that are heart-shaped and deeply lobed, growing on long petioles. They are often tinged reddish purple.
Blooming in spring, summer and fall, Creeping Oxalis features flowers with 5 yellow petals forming in clusters of 1 - 5 at the end of its slender stems. Reproduction is by seed and stolons that root at the nodes. Creeping Oxalis can be distinguished from Oxalis by its more horizontal growth habit.
Creeping Oxalis Control -
Proper cultural practices, such as proper mowing and watering, can help to prevent Creeping Oxalis by creating dense turf, which inhibits the weed’s ability to grow. Physical removal (i.e. “weed pulling”) can be effective, although you will run the risk of spreading the seeds to additional areas of your lawn and landscaping.
