Appearance
Anthriscus sylvestris is an herbaceous biennial that grows up to 3.25 ft. (1 m) in height. The stems are hollow and covered in hairs. Anthriscus sylvestris is native to Europe.
Foliage
The plant has alternately arranged, compound, fern-like leaves. Each segment of the leaf can measure 0.5-2 in. (1.5-5 cm) in length.
Flowers
The umbels of this plant are large, having 6-15 rays that can reach up to 1.5 in. (4 cm) in length. Each of the bractlets is lance-ovate in shape and measures 0.1-0.25 in. (3-6 mm) in length. The flowers are white and have 5 notched petals. Anthriscus sylvestris blooms from May to June.
Fruit
The fruits are smooth, lanceolate in shape and measure 0.25 in. (6 mm) long. They have a pronounced beak that measures 0.04 in. (1 mm) long. The fruits start out green and turn brown as they ripen.
Ecological Threat
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.
