The leaves are bright green, often hairy along the edges, and clasp the stem. Flowers emerge in late summer and are characterized by a greenish to purple inflorescence with up to ten “fingers.”

Small carpetgrass prefers well lit, moist areas and thrives in disturbed wetland and riparian areas.
Threats & Impacts:
Small carpetgrass is a quick growing perennial that can reproduce via prolific seed production as well as vegetatively via rooting at nodes. This quick growth coupled with its ability to reproduce quickly allows small carpetgrass to quickly form monocultures, excluding native plants.
Small infestations can be managed by hand pulling prior to seed set. Be sure to bag and solarize all plant material prior to disposal in a landfill. Larger infestations can be treated using a selective foliar spray of herbicide or via mowing while small carpetgrass is in flower but before seed set.
