Alopecurus myosuroides, commonly known as slender meadow foxtail, black-grass, or twitch grass, is an annual grass that is native to temperate regions of Eurasia. It is typically found in moist meadows, along riverbanks, in open fields, and occasionally in deciduous forest clearings, as well as in cultivated fields and disturbed sites. This grass usually grows to a height of up to 31 inches (80 cm) and is characterized by its hairless leaves, smooth leaf sheaths, and pointed leaf blades. The inflorescence is a cylindrical spikelet, ranging in color from yellow-green to purple, which blooms from May to August and is quite noticeable due to its distinctive bristly appearance.

Slender meadow foxtail is often considered a weed in agricultural settings due to its rapid growth and ability to compete with crops. However, it can be used for soil stabilization and as a temporary ground cover in non-cultivated areas. It prefers moist, fertile soils and can tolerate a range of light conditions from full sun to partial shade. While it is not typically grown for ornamental purposes, its presence can indicate soil health and moisture levels. Gardeners should be cautious as it can become invasive outside its native range, particularly in similar temperate climates.CC BY-SA 4.0
