Dactylis

Dactylis is a genus of grasses in the Poaceae family. The best-known member is Dactylis glomerata, commonly called cocksfoot or orchard grass. Native to Europe, western and central Asia, and northern Africa, it has been widely introduced and naturalized in temperate regions as a forage crop. The genus includes several species, but D. glomerata is by far the most commonly cultivated for pasture and hay.

Dactylis glomerata is a perennial, tufted (bunch) grass that forms dense clumps. It typically reaches 60–120 cm in height and has tall, narrow leaves with a bluish-green hue. The inflorescence is a large, branched panicle with spikelets arranged in compact clusters called glomerules. The species is dioecious? No, grasses are monoecious or have perfect flowers; D. glomerata flowers in late spring to summer and can spread by seed and vegetative tillers.

Habitat and ecology: It prefers well-drained, fertile soils but tolerates a range of soil types. It handles cold temperatures and moderate drought once established and is commonly found in temperate pastures and meadows. As a forage grass, it forms a durable sward and responds positively to grazing and appropriate fertilization. It is typically more of a tussock-forming grass rather than a creeping sod and can dominate a stand if not managed with rotational grazing or timely reseeding.

Cultivation and uses: Dactylis glomerata is grown primarily for forage, used in pastures, hay, and silage systems in temperate livestock production. It is often included in seed mixtures with other grasses and legumes to improve yield and quality. Management practices emphasize timely grazing, soil fertility, and reseeding to maintain persistent stands.

Taxonomy: The genus name Dactylis derives from Greek for “finger,” alluding to the clustered spikelets characteristic of the group.
