Habitat: This annual grass is generally associated with moist, rich soils. It survives at varying levels of soil acidity and can tolerate lighting from full sun exposure to deep shade. Common establishment locations include moist woodlands, roadside ditches, early successional fields, and stream banks.

Native Range: China, Japan, Korea, Malaysia, and India

U.S. Distribution: Japanese stiltgrass has been introduced to the southeast region of the U.S. as far north as New York and as far west as Texas.

Local Concern: Stiltgrass spreads opportunistically after a disturbance. It forms dense patches and displace native understory vegetation as the patches expand.
