AuthorL.
DistributionAcross the state, but apparently sparse on the Coastal Plain. No doubt will be found in many other counties.

Native of Mexico, W.I., C.A., S.A.; in N.A. essentially throughout southern Canada and the US.
AbundanceFairly common to common in the Piedmont and Sandhills; uncommon elsewhere. However, no doubt overlooked, as there are similar native species that occur in weedy places, especially O. dillenii and O. stricta.
HabitatRoadsides, driveways, sidewalk cracks, lawns, campus weed, flower beds and gardens, waste areas, etc.
PhenologyFlowering February-May, sparingly to November.
IdentificationCreeping Woodsorrel does indeed creep, the stems rooting at the nodes and rather prostrate. Plants thus often form mats. The flowers are markedly smaller than our other species, yellow, and short-stalked.
