Common Briar

How to grow Common Briar

Written by the GardenDecoded editorial team · Last reviewed 21 July 2026 · Written for UK gardens · How we research our guidance

Planting

A native scrambling rose for hedgerows and wild boundaries rather than a border. Plant bare-root in winter, mixed through a native hedge where it can lean on other shrubs.

Pruning

It needs no formal pruning. Cut it back as part of hedge management in late winter, before birds start nesting.

Propagation

Hardwood cuttings in autumn, or sow seed from the hips after a long cold period. Germination is slow and often spread over two winters.

Pests and diseases

Blackspot, rust and mildew all occur but rarely matter on a plant grown informally. Robin's pincushion galls are harmless.

Value to wildlife

High. Single open flowers give pollen to a wide range of bees, the hips feed birds through autumn and winter, and the thorny growth makes good nesting cover.

Notes

Vigorous and thorny — it will take over a small border. It is also the traditional rootstock for budded roses, so suckers from the base of a grafted rose are often this.
