There are more than one-hundred species of fescues worldwide. Some are annuals while others are perennials. Annual species are usually considered weeds. Six perennial fescues are managed either alone or in turf mixtures in the U. S. Presently, tall fescue (Festuca arundinacea Schreb.), classified as a coarse fescue, is the primary cool-season species used as turf in Tennessee. Strong (Festuca rubra L. rubra) and slender creeping red (Festuca rubra L. ssp. trichophylla, Festuca rubra var. littoralis Vasey), chewings (Festuca rubra L. ssp. falax Thuill., Festuca rubra L. var. commutata Gaud.), hard (Festuca brevipila R. Tracey) and sheep (Festuca ovina L.) fescues are collectively referred to as fineleaf or fine fescues due to their narrow leaves. Because they generally perform better than tall fescue in low light, the fine fescues are commonly recommended for use as cool-season turfs in medium to moderate shade in northwest, north central and upper east Tennessee. A lack of heat tolerance limits the use of these species in shade in other areas of the state in which summer temperatures are much higher. They are also valued for their fibrous root systems when used as components of ‘meadow mixes’ along with legumes, wildflowers and/or native plants. Left unmowed, fine fescues often reach a height of 6–12 or more inches. Seeds of many improved, turf-type coarse and fine fescues contain beneficial fungi, or endophytes, that live between cells inside plants. Endophytes may improve the plants’ ability to withstand heat stress and enhance disease resistance (for example, dollar spot (Lanzia and Moellerodiscus spp.) in fine fescues). They also produce compounds capable of reducing the feeding activity of certain insect pests. Endophytes are transmitted from generation to generation in seed, and do not move from one plant to another by way of pollen.
