Ecology

A perennial herb with creeping woody stems occurring in chalk and limestone districts in two distinct habitats. Inland, it grows in woodland edges and rides, and on lanesides and banks in partial shade. On the coast, it is found amongst naturally dwarfed, open scrub on slumped cliffs, slopes and crags. It spreads by seed and from the stems rooting at nodes. It also occurs as a garden escape on roadsides and waste ground. Lowland.
