About

Black bryony is a climbing hedgerow and woodland edge plant that flowers between May and August. Later on, it produces red, shiny berries that can be seen in autumn and even early winter. Our only native member of the yam family, Black Bryony is actually highly poisonous. Despite its name and superficial resemblance, it is not a relative of White Bryony.

What to look for

Black bryony is a twisting climber, but lacks the tendrils of the similar-looking White bryony. Its leaves are heart-shaped and glossy, and their veins form a net pattern. Black bryony displays yellow-green, six-petalled flowers and shiny, red berries.

Where to find

Mainly found in England and Wales.

Did you know?

Black bryony grows from a tuber (a modified root that stores nutrients) that develops about 10-20cm below the soil. This tuber can grow very large, reaching 60cm width and is, like the rest of the plant, highly poisonous.
