Agrostis gigantea, commonly known as Black Bent or Redtop, is a perennial grass originally native to temperate regions of Europe and Asia but has been introduced to North America and other regions. It typically grows 16-47 inches tall with a clumping habit and features dull green, narrow leaves. The plant produces open, loose panicles with small, wind-pollinated flowers that bloom from June to August, though the flowers are not particularly showy. In its native habitat, Agrostis gigantea is found in a variety of settings including meadows, open woodlands, grasslands, and along riverbanks, where it often forms a significant component of the ground cover.

Black Bent is valued for its adaptability to a range of soil types and conditions, including poor soils, and its ability to tolerate both drought and temporary flooding. It is used for erosion control, as a turf grass in lawns, and as forage for livestock. In cultivation, it prefers full sun to light shade and can handle a variety of soil conditions, from moist to well-drained. While it was once a popular pasture grass, its use has declined due to the availability of more productive species. However, it remains a useful species for revegetation and restoration projects. Gardeners should be aware that Agrostis gigantea can be invasive outside its native range and should check local regulations before planting.CC BY-SA 4.0
