Scientific NameMollugo verticillata
Synonyms (former Scientific Names):
Germination begins late spring to early summer; however, the plant has very rapid growth and begins flowering as early as June and as late as September. It grows in a mat with a taproot.
Leaves are sessile, smooth and either rounded above and narrowed to the base or widest above the middle and tapering to the base (spatulate). They appear in whorls of 3-8 at each stem node.
The plant forms prostrate mats along the ground (which resembles a carpet). Green Carpetweed is easily identified by its whorled leaves.
Flower Seed Head

Fruit are small egg-shaped capsules with three chambers. The seeds harbored in those chambers as very small, dark brown, flattened, and kidney-shaped.
Carpetweed can infest bare areas in thin turf, agronomic crops, flower beds, and gardens. It is more abundant on moist rich soils.
