Wild chervil is a herbaceous biennial or short-lived perennial from the parsley family, introduced to North America from Europe. It was first brought to North America as part of European wildflower seed mix used for plantings along hedgerows and meadows.
This species is short-lived, forming a rosette of only leaves in the first year, then flowering and producing seeds in the second year. As a heavy seed producer, it is easily spread to new locations. Wild chervil has few checks on its population in North America and can quickly take over an area, displacing native species and forming dense stands that are difficult to control.
