About

Hogweed is a native plant (unlike its alien relative, giant hogweed) which is abundant in hedgerows, roadside verges, waste grounds and rough grasslands. As a member of the carrot family (an umbellifer), it displays large, umbrella-like clusters of creamy-white flowers between May and August (although it can flower all year-round) which are attractive to a range of insects.

Although they might not look especially wildlife-friendly, our roadside verges, railway cuttings and waste grounds can provide valuable habitats for all kinds of plants and animals.

What to look for

Hogweed displays large, white umbels of flowers, and has hollow, hairy stems. Its leaves are broad, hairy and divided. It is not as tall as giant hogweed.

Where to find

Widespread.

Habitats

Did you know?

The hollow stems of hogweed were traditionally used in many children's games as water guns, pea-shooters and swords. Its sap is less toxic than that of giant hogweed (and some other umbellifers), so doesn't cause the same skin irritation.
