Bentgrass

Japanese: ベントグラス（英語表記）bentgrass

A general term for evergreen perennial plants of the Agrostis genus of the Poaceae family that are used as turfgrass and pasture grass. They are found in the temperate and subarctic zones of the Northern Hemisphere. They prefer cool climates and have poor heat resistance, so in Japan it is difficult to plant them outside of Hokkaido and northern Tohoku, where poor growth and disease caused by high temperatures and humidity in summer and subsequent dryness are problems. They are a representative species of turfgrass in central and northern Europe, but are not common in Japan. They are sometimes used for lawns in gardens and parks in northern Japan, and are often used for golf course greens due to their evergreen nature, but they are difficult to maintain, and disease control is particularly difficult.

イネ科コヌカグサ属Agrostisの常緑多年草で，芝草や牧草として利用されるものの総称。北半球温帯，亜寒帯に分布する。冷涼気候を好み，耐暑性が弱く，日本では北海道，東北北部以外では植栽は難しく，とくに夏季の高温多湿とその後の乾燥による生育不良と病害が問題となる。欧米の中北部の芝草の代表種であるが，日本では一般的でない。北日本の庭園，公園の芝生用に使われることがあり，またその常緑性からゴルフ場のグリーンに多く使われるが，その維持管理は難しく，とくに病害防除に苦労が多い。
