COMMON NAME: Orchard Grass

Plant Profile

Orchard Grass, or cocksfoot, is a tufted perennial grass of Europe and temperate Asia, forming bold clumps of soft, flat, grey-green leaves up to a metre tall. Its seed heads are compressed and one-sided, carried high in early summer, and the clumps hold their bulk through the season.

It has fed stock in temperate fields for two centuries and is one of the world’s great hay grasses. Its particular trick is shade tolerance: it is the productive grass of orchards, woodland edges and north-facing banks, which is where its English name comes from. The clumps are coarse rather than elegant, and they are best given a position where their bulk is useful, at the back of a wild border or on a bank that needs holding.

Science & Biotechnology

It is an outcrossing tetraploid with wide variation, and breeders have selected it for maturity classes, disease resistance and grazing tolerance across the temperate world. Ecologically it is a competitor: deep-rooted and drought-tolerant, it dominates a sward unless managed, which is why mixtures balance it with fescues and ryegrass.

The compressed, boat-shaped flower heads are a field identification landmark, and the grass is one of the standard subjects of temperate pasture science. Its shade tolerance has a physiological basis that has been measured: the leaves photosynthesise usefully at light levels that close down ryegrass, which is why it thrives under orchard canopies. Seed lots carry endophyte variation like the other hay grasses, and breeders have selected lines without the alkaloid load that puts stock off the feed.

Uses & Benefits

Sown for hay or grazing, it gives an early, bulky cut and stands drought that ryegrass cannot. In the garden it is an honest meadow grass for a wilder lawn or orchard floor, cut once or twice a year, and its clumps hold banks against erosion.

For pollinators it is modest, but its seed heads and cover serve birds, and its early growth makes it the first green of the spring field. Farmers value its first cut for early hay and its regrowth for aftermath grazing, a pattern that suits a rotation better than a single-use sward. Its clumps also provide early cover for ground-nesting birds in a wilder meadow, arriving before most of the finer grasses have bulked up.

Growing from Seed

Sow the seed in spring or early autumn, five to ten millimetres deep in a firm seedbed, alone at a heavy rate or in mixtures at a few kilograms to the hectare.

Keep the surface moist through germination, which takes one to two weeks in warmth; the seedlings are strong from the start.

First cut when the heads just emerge for the best feed, and let the clumps recover between cuts; it wants nitrogen and responds to it, and a closed sward keeps it from swarming. In the garden, one clump is enough; divide it in spring with a spade and replant the outer pieces to renew it.

Our Take

The orchard’s own grass: shade-tolerant, drought-proof and bulky, the reliable engine of a hay meadow or a rough orchard floor.
