Bur chervil

Anthriscus caucalis

About This Species

Bur chervil (Bur parsley) is an herbaceous plant that is native to Europe and can be found in most growing conditions, particularly in moist or disturbed areas such as roadsides, meadows, or riparian areas. Bur chervil’s flowers produces two bur-like seeds that have a pronounced peak and are covered in bristles that easily stick to humans and animals to spread.   

It easily out-competes native vegetation forming monocultures and reducing natural biodiversity. Each Bur chervil is designated as a Provincial Noxious Weed by the BC Weed Control Act, as well as a Management species by the BC Provincial Priority Invasive Species List. 

How to Identify

Bur chervil is an herbaceous plant that is generally around 30 cm, but can range in height from 1-2 m tall while flowering. Stems are hollow and the stem nodes have a fringe of hairs. 

Flowers are small and white, in clusters of 3-7 atop 2 cm long stalks. The seeds are approximately 4 mm long with distinctly hooked prickles. 

Leaves are alternate arranged, triangular, and fern-like in appearance. Young leaves are generally hairy.
