Tall Fescue

Festuca arundinacea

Festuca arundinacea (syn., Schedonorus arundinaceus andLolium arundinaceum) is a species of grass commonly known as tall fescue. It is a cool-season perennial C3 species of bunchgrassnative to Europe. It is an important forage grass throughout Europe, and many cultivars have been used in agriculture. It is also anornamental grass in gardens, and a phytoremediation plant.

The predominant cultivar found in British pastures is S170, anendophyte-free variety. In its native European environment, tall fescue is found in damp grasslands, river banks, and in coastal seashore locations. Its distribution is a factor of climatic, edaphic, or other environmental attributes

Tall fescue is a long-lived perennial bunchgrass species. Photosynthesis occurs throughout the leaves, which form bunches and are thick and wide with prominent veins running parallel the entire length of the blade. The blades have a "toothed" edge which can be felt if fingers are run down the edge of the leaf blade. The underside of the leaf may be shiny. Emerging leaves are rolled in the bud with no prominentligule. Note that most grasses are folded not rolled, which make this a key identification feature on tall fescue. The auricles are usually blunt but occasionally may be more clawlike. The culm is round in cross-section. Typically, this species of grass has a long growing season and ranges between 2 to 4 feet (1.2 m) tall in seedhead stage.

Tall fescue spreads through tillering and seed transmission — not by stolons or rhizomes, which are common in many grass species. However, tall fescue may have numerous sterile shoots that extend the width of each bunch. There are approximately 227,000 seeds per pound.

Typically found across the mid-Atlantic and Southeast US, tall fescue performs best in soils with pH values between 5.5 to 7. Growth may occur year-round if conditions are adequate, but typically growth ceases when soil temperature falls below 40 °F (4 °C)
