Small carpetgrass is an annual grass that was introduced into the United States, either accidentally or by immigrants, from Japan and eastern Asia. The plant stands to 1.5 ft. (0.5 m) tall with oval to lance-shaped leaves. Leaves are 1-3 in. (2.5-7.6 cm) long, 1/5 in. (0.5 cm) wide and have heart shaped bases. The margins of the leaves have conspicuous hairs. Flowers bloom in early fall and are contained in 1 to several, 1-3 in. (2.5-7.6 cm) long spikes. Small carpetgrass inhabits wet areas such as stream banks, flood plains and shorelines.
