A bushy shrub naturalised in shaded habitats, and occasionally also in more open places where its growth is often stunted. Lowland.
H. hircinum was being grown in Britain by 1640, and had been recorded in the wild by 1856. Dunn (1905) described it as `naturalised in many situations`. It does not appear to spread rapidly into natural vegetation. There are more records than in the 1962 Atlas, but there is no real sign of spread.
A native of the Mediterranean region; naturalised in W. Europe.
