Tall Fescue (Festuca arundinacea)
Tall Fescue (Festuca arundinacea) is a vigorous perennial, with both bunch type and rhizomatous growth habits. It is extremely deep-rooted providing excellent tolerance to drought but will also tolerate wet soils and short periods of water logging. Tall fescues form a dense resilient sward that is quick to establish and recovers easily from wear.
