Mollugo verticillata aka Indian Chickweed

Mollugo verticillata, also known as green carpetweed or Indian chickweed, is a rapidly spreading summer annual plant native to tropical America. It forms a prostrate circular mat that can quickly climb over nearby plants and obstacles. In eastern North America, it is a common weed growing in disturbed areas such as tilled gardens, newly planted lawns, and along roadsides. The plant has been reported from every state in the United States except Alaska, Hawaii, and Utah, as well as from British Columbia, Manitoba, Ontario, Quebec, New Brunswick, and Nova Scotia. Although considered an invasive weed, M. verticillata is also known to be edible and has been in North America for about 3000 years, as evidenced by archaeological findings. The leaves are not glaucous and grow in whorls of 3-8 with a basal rosette, sometimes disappearing as the plant matures. The flowers grow in sessile, axillary umbels and are sepals that are green on the underside and white on the upper side. The capsules are ovoid-ellipsoid and the seeds are dark or reddish brown, with blackish, parallel, curved ridges on the sides or smooth. Carpetweed can be easily removed by pulling or hoeing. In China, this plant is referred to as zhong leng su mi cao.
