The following species in the grass genus Festuca, the fescues, are accepted by Plants of the World Online as of 2024. [1] This genus together with the ryegrass genus Lolium form the Festuca–Lolium complex known for its frequent hybridization, and which is further complicated by the presence of a fine-leaved fescue clade within Festuca that appears to be sister to a clade consisting of Lolium ...
Festuca altaica, also known as the altai fescue, or the northern rough fescue, is a perennial bunchgrass with a wide native distribution in the Arctic, from central Asia to eastern North America.

[3] The stiff, short, rolling leaves are mostly located near the base of the tuft. The inflorescence has hairy spikelets which produce large awned fruits. The root system is thick and penetrates ...
Tall fescue is the most heat tolerant of the major cool season grasses. Tall fescue has a deep root system compared to other cool season grasses. This non-native grass is well adapted to the "transition zone" Mid Atlantic and Southeastern United States and now occupies over 35,000,000 acres (140,000 km 2). [23]
Festuca viridula is a species of grass known by several common names, including green fescue, greenleaf fescue, and mountain bunchgrass. It is native to western North America from British Columbia to Colorado , where it is most abundant in high-elevation forests and meadows.
