What is Dactylis glomerata

Oorchard grass, cock's-foot glass or cocksfoot ,Scientific name: Dactylis glomerata, is a hardy perennial grass native to the Mediterranean region and West Asia. It belongs to the Poaceae family and the genus Dactylis. In Japan, it is called Kinu-itosou (絹糸草), which translates to "silk thread grass." The plant was introduced to Japan as a forage grass from the United States in the early Meiji period (1860s).
In Japan, cocksfoot (Dactylis glomerata) grows wild and spreads across farmlands, grasslands, riverbanks, and vacant lots in Hokkaido, Honshu, Shikoku, Kyushu, and Okinawa.
The grass reaches a height of 80–100 cm. Its leaves are green, linear, 10–40 cm in length, and 0.5–1 cm in width.
From May to July, it produces panicle inflorescences 8–20 cm long, bearing spikelets approximately 0.8 cm in length.
Cocksfoot is used for various purposes, including forage grass, roadside slope greening, and golf course turf. Unfortunately, its pollen is a known allergen and can cause hay fever.
