Safety Overview
1.Anthriscus Sylvestris — Plant Snapshot
Anthriscus sylvestris, commonly known as Cow Parsley, Wild Chervil, or Keck, is a widespread herbaceous biennial or short-lived perennial belonging to the Apiaceae (Umbelliferae) family. This species typically grows upright, reaching heights of 60 to 170 centimeters. Its stems are distinctly hollow, striate (striped with longitudinal lines), and furrowed, appearing green with occasional purple flushes and covered in tiny, often difficult-to-see hairs.
The leaves are triangular, 2-3 pinnate, giving them a fern-like or feathery appearance, and can measure approximately 30 cm wide by 45 cm long, with noticeable hair on their undersides. The plant’s characteristic white flowers are arranged in delicate compound umbels, each supported by short pedicels, often featuring downy oval bractioles with reddish tips.
Native to Europe, western Asia, and northwestern Africa, Anthriscus sylvestris thrives in a variety of environments, from sunny meadows and the edges of hedgerows to semi-shaded woodlands and roadsides. Its rapid growth and ability to spread effectively via both rhizomes and prolific seed production have led to its classification as an invasive species in several regions outside its native range, including parts of the United States (e.g., Vermont, Massachusetts, Washington State) and Iceland.
The species was initially described by Carl Linnaeus in 1753 as Chaerophyllum sylvestre before being reclassified into the genus Anthriscus by Georg Franz Hoffmann in 1814. It is frequently confused with other members of the Apiaceae family, most notably Wild Carrot (Daucus carota) and, critically, highly toxic species such as Poison Hemlock (Conium maculatum), necessitating extreme caution in identification.
