The climber with glossy heart-shaped leaves that goes up hedges by twining its stem, with no tendrils at all, and in autumn covers itself in showy clusters of red berries. The berries are toxic and attract children.

Where it grows

Oak woods · Roadsides and waste ground · Walls and rocks · Streams and ditches

Also known as

lady's seal, black bindweed

In fruit

How to tell it

A heart-shaped, entire, glossy leaf with veins all radiating from the base and converging at the tip, which is rare and very characteristic. A stem that twines on its own, with no tendrils. Translucent red berries in hanging clusters.

What it is confused with

White bryony

Bryonia dioica

Confusion that poisons

Both climb the same hedge and both bear toxic red berries. White bryony has spiral tendrils and a rough five-lobed leaf; black bryony has no tendrils and an entire, smooth, glossy leaf.

What it is for

The young shoots are eaten in Spain, boiled with the first water thrown away, and sold in markets as espárragos de nuez. It carries no edible tag here on purpose: the same plant has very toxic berries and root, and a use that depends on getting the part and the preparation right is not a use for a field guide.
