is a deciduous shrub, up to 2 m in height which spreads by suckering and putting
out slender arching stems into woodland and woodland margins. It also grows
along hedges on neutral, lime-rich and heavy clay soils.
The long scrambling stems are often purple-tinged and carry slender, only slightly curved, prickles on a base about 5 mm long.
The white, 5-petalled flowers are 3-5 cm across, and appear in clusters of 1-6 and open in June and July. The styles in the centre of the flower are joined together into a slender column, which persists on the small, red hip.
