Oenanthe pimpinelloides is a species of flowering plant in the carrot family
known by the common name corky-fruited water-dropwort.
It is native to Europe, the Middle East, and parts of western Asia and North Africa, and it is known on other continents as an introduced species
and sometimes a noxious weed. This is a perennial herb growing to a maximum height near one meter. The leaves have blades up to 12 centimeters long borne on petioles
up to 10 centimeters in length. The leaf blade is divided into leaflets which are subdivided into smaller segments which may be lobed or deeply cut. The inflorescence
is a compound umbel
of many flowers with bright white to red-tinged petals.
Frequently the plant grows on acidic soils. It is able to stand both dry and damp environments.
