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.
"Warm season turf grasses generally go dormant during the winter months," says Harlow. "If they are in Zones 9B -11, they may not go dormant at all." Cool-season grass may continue to grow in ...
Almost all ornamental grasses are perennials, coming up in spring from their roots, which have stored large quantities of energy, and in fall or winter go dormant.Some, notably bamboos, are evergreen, and a few are annuals.
Native grasses (cool season) such as bluegrass and tall fescue, are greenest in the spring and fall and go dormant in the high heat of the summer. New cultivars of bluegrass, such as Reveille, and tall fescue, can reduce typical bluegrass water requirements by at least 30%.
Warm season grasses only start growth at temperatures above 10 °C (50 °F), and grow fastest when temperatures are between 25 °C (77 °F) and 35 °C (95 °F), with one long growth period over the spring and summer (Huxley 1992). They often go dormant in cooler months, turning shades of tan or brown.
Festuca (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of 10–200 cm (4–79 in) and a cosmopolitan distribution , occurring on every continent except Antarctica . [ 2 ]
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.
Dormancy is a general term applicable to any instance in which a tissue predisposed to elongate or grow in some other manner does not do so (Nienstaedt 1966). [9] Quiescence is dormancy imposed by the external environment.
