M. reptans of Michigan Flora.
A native of Asia cultivated as a perennial ground cover for its attractive blue flowers; occasionally becoming a lawn and garden weed; first collected in 1976 in Berrien Co.
The plant has abundant, very slender stolons, and roots freely at the nodes. Plants of Kickxia and Cymbalaria in the Plantaginaceae, with similar prostrate habit might be keyed here if one fails to note the spur on the corolla of those two; however, the corollas of Mazus, besides lacking a spur, are much larger (over 1 cm and as much as 2.6 cm long). A white form is also commonly cultivated and also escapes.
