Ecology

A perennial herb with creeping stems, R. repens has a very wide ecological tolerance, but is most typical of disturbed habitats on damp or wet nutrient-rich soils, including woodland rides, ditch sides, farm gateways, gardens and waste ground. It also occurs in damp or periodically flooded grasslands, in dune-slacks and on lake shores. It is absent from very acidic soils. Generally lowland, but reaching 1035 m on Snowdon (Caerns.).
