Timothy-grass
Timothy-grass (Phleum pratense), is an abundant perennial grass native to most of Europe except for the Mediterranean region. It grows to 50–150 cm tall, with leaves up to 45 cm long and 1 cm broad. The flowerhead is 7–15 cm long and 8–10 mm broad, with densely packed spikelets. Additional recommended knowledgeTimothy-grass can be confused with Meadow Foxtail (Alopecurus pratensis) and Purple-stem Cat's-tail (Phleum phleoides). There are two subspecies:
Cultivation and usesTimothy-grass was unintentionally introduced to North America by early settlers, and was first described in 1711 by John Herd from plants growing in New Hampshire. Herd named the grass "herd grass" but a farmer named Timothy Hanson began to promote cultivation of it as a hay about 1720, and the grass has been known by its present name since then. It is commonly grown for cattle feed and, in particular, as hay for horses. It is relatively high in fibre, especially when cut late. It is considered part of the standard mix for grass hay and provides quality nutrition for horses. Timothy Hay is a staple food for domestic pet rabbits, guinea pigs, and degus, often making up the bulk of their diet. The caterpillars of some Lepidoptera use it as a foodplant, e.g. the Essex Skipper (Thymelicus lineola). Its pollen is a common allergen; It has recently been used in small amounts as part of a new hay fever vaccine Grazax, which is designed to recondition the body's immune system so it no longer responds to pollen.
