Parsley Dropwort

Oenanthe pimpinelloides

Parsley dropwort is an invasive pasture weed which causes major problems where it grows.

Distinguishing features
The two weeds that parsley dropwort are most likely to be confused with are hemlock and wild carrot, both also weeds from the Apiaceae family. All three of these weeds have white flowers in the form of umbels on top of upright flower stems. The best way to tell them all apart is to closely study the leaves. The leaf shape of parsley dropwort is shown in the side picture. It is made up of leaf segments quite different in shape to hemlock, which is quite fern-like in shape, and also different to wild carrot which has leaves almost exactly the same as the cultivated carrot, which have much finer leaf segments. It is sometimes also confused with yarrow, but this also has very fine leaf segments. Parsley dropwort has little swollen tubers on its roots, though these often aren't very noticeable. These tubers allow the plant to regrow again following control attempts.
