Overview

Red fescue (Festuca rubra) can establish in arable land but does not persist with cultivation. It is commonly found in field edges and many other relatively undisturbed habitats. Red fescue grows rapidly in spring after overwintering. It can also reproduce vegetatively when the rhizomes which attach child plants die.

  • It has value to biodiversity

Description

It is a densely tufted perennial grass, 15–90 cm tall. It spreads by rhizomes. The leaves are green or greyish-green and bristle-like. The flowerhead tapers to a point but is rather one-sided.

Key features

Plant: Stems are red at the base.




Location and life cycle

Geographic distribution

Red fescue grows over the whole of the British Isles in many grassy habitats such as road verges, meadows and pastures up to an altitude of 1,080 m. It has many varieties.

Soil type

It grows in alkaline-rich soils and even rocky habitats, but is not usually found where there is a large amount of exposed soils.

Seed statistics

  • Seed longevity: 1–5 years
  • Seed weight: 1 mg
  • Seeds/head: 100
  • Seeds/plant: 10

Management

It is relatively tolerant of foliar-acting herbicides because of its bristle-like leaves reducing uptake, so high doses are generally required.

For advice on herbicides, please speak with your agronomist or adviser.
