Botanical Description
Microstegium vimineum, Japanese stiltgrass or Chinese packing grass, is a sprawling annual grass in the family Poaceae native to East and South Asia and now a highly invasive species in much of eastern North America, where it carpets shaded forest floors, stream banks, trail edges, and disturbed woodland soils. Plants are 30–100 cm long, with slender, weak, branched stems that bend along the ground and root at the lower nodes before turning upward at the tips; isolated plants form loose tufts while crowded populations create dense mats. The leaf blades are pale green, lanceolate, 3–9 cm long and 5–15 mm wide, asymmetrically tapering to a short petiolule-like base, and have a distinctive silvery midrib offset slightly to one side. Inflorescences are slim, digitate clusters of one to three (sometimes more) terminal and axillary spikelike racemes 3–7 cm long that emerge above the foliage in early autumn. Spikelets occur in pairs and bear a short, often inconspicuous, geniculate awn. The species is shade-tolerant, prolific, and forms persistent seed banks.
