About

Hop is a sun-loving, climbing plant that is most famous for its role in beer-making. It rambles through woodland, field edges, hedgerows and waste ground, growing in sunny areas. Hop bears male and female flowers on different plants: the male flowers are small, but the female ones are like large, scaled apples and are unmistakeable. Glands within these flowers contain essential oils and have a distinctive, yeasty-garlic smell.

How to identify

A scrambling climber of hedges, Hop has nettle-like, deeply lobed leaves. Its flowers are greeny-yellow; male flowers grow in loose groups, while female flowers are catkins, shaped like a cone. It is the female flowers that turn to fruit, which are cone-shaped and brown when ripe.

Distribution

Found throughout the UK, but most common in England.

Did you know?

Until the end of the Middle Ages, other plants were being used to preserve and flavour beer, but the flower cones of Hops enabled beer to be preserved for longer and gave the ale a distinctive taste. By the end of the 16th century, beer-drinking was popular across England and Hops were grown extensively for its production.
