Festuca paradoxa, the cluster fescue, is a cool-season grass native to Canada and the Continental United States. Like other cool-season grasses, it grows during the spring and fall, and remains dormant for the rest of the year. This helps maintain ground cover before the warm season grasses begin to grow and after they die off.
The signs of the virus begin to become visible when the leaves at the top of the plant begin turning yellow and eventually fall off. [6] This usually occurs in the upper third of the canopy and death of the plant usually occurs soon after the leaves wilt and die. [ 3 ]

Festuca californica is a species of grass known by the common name California fescue.. This fescue species is native to the U.S. states of California and Oregon, where it is a member of many plant communities, including chaparral and oak woodlands, the former of which can be found in both Northern and Southern coastal California and the latter in Central and Northern California.
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. It was first described in 1829 by Carl Bernhard von Trinius. [2] [3] It is under the synonym F. scabrella, the rough fescue. [4]
Festuca rubra, as red fescue or creeping red fescue, is cultivated as an ornamental plant for use as a turfgrass and groundcover. It can be left completely unmowed, or occasionally trimmed for a lush meadow-like look. There are many subspecies, and many cultivars have been bred for the horticulture trade.
Tall fescue is a long-lived tuft-forming perennial with erect to spreading hollow flowering stems up to about 165 cm (5'6") tall (exceptionally up to 200 cm) which are hairless (glabrous), including the leaf sheaths, but with a short (1.5 mm) ligule and slightly hairy (ciliate) pointed auricles that can wrap slightly around the stem.
The reduction of chlorophyll production in leaves due to decreased sunlight in the autumn explains why some leaves turn yellow. However, the yellow color can attract aphids, so some trees turn the leaves red instead by injecting a bright pigment. [8] The loss of chlorophyll may also contribute to the abscission process.
