Anthriscus sylvestris, known as cow parsley, wild chervil, wild beaked parsley, or keck is a herbaceous biennial or short-lived perennial plant in the family Apiaceae, genus Anthriscus. It is also sometimes called mother-die.
Anthriscus sylvestris is native to Europe, western Asia and northwestern Africa; in the south of its range in the Mediterranean region, it is limited to higher altitudes. It is related to other diverse members of Apiaceae, such as parsley, carrot, hemlock and hogweed. It is often confused with Daucus carota which is known as Queen Anne's lace or wild carrot, also a member of the Apiaceae. The hollow stem grows to a height of 60–170 cm (24–67 in), branching to umbels of small white flowers. Flowering time is mid spring to early summer. Cow parsley grows in sunny to semi-shaded locations in meadows and at the edges of hedgerows and woodland. It is a particularly common sight by the roadside. It is sufficiently common and fast-growing to be considered a nuisance weed in gardens.
