Anthriscus sylvestris is a herbaceous biennial that grows up to 3.25 feet in height. The stems are hollow and covered in hairs.
The plant has alternately arranged, compound, fern-like leaves. Each segment of the leaf can measure 0.5-2 inches in length.
The umbels of this plant are large, having 6-15 rays that can reach up to 1.5 inches in length. Each of the bractlets is lance-ovate in shape and measures 0.1-0.25 inches in length. The flowers are white and have 5 notched petals. Anthriscus sylvestris blooms from May to June.
The fruits are smooth, lanceolate in shape and measure 0.25 inches long. They have a pronounced beak that measures 0.04 inches long. The fruits start out green and turn brown as they ripen.

Native to Europe
Abandoned Field, Agricultural Field, Edge, Open Disturbed Area, Pasture, Yard or Garden. Anthriscus sylvestris grows well in rich moist soils and is most commonly found along roadsides, meadows, and pastures. It is particularly problematic in hayfields and pastures in central Vermont
Anthriscus sylvestris can reproduce both by seed and by vegetative means. Vegetatively, it makes use of aggressive, fast spreading taproots that have lateral root buds capable of sprouting new plants.
Anthriscus sylvestris may be transported by vehicles, particularly those used to mow it down after it has set seed, as well as people, animals, and wind. Since it is tall and grows aggressively, it may outcompete native vegetation by forming extensive stands resulting in shading of other species, and by utilizing resources more effectively.
