Geranium sanguineum

Ecology

A rhizomatous, perennial herb of base-rich grasslands and scrub, open rocky woodlands, coastal cliffs and stabilised sand dunes; mainly on the coast but also inland on limestone pavements and cliff ledges, and in chalk and limestone grassland. As a native it has a curiously patchy distribution, and is often restricted to localised substrates such as dolerite and serpentine. It also occurs as a garden escape or throw-out on grassy banks, verges, tips and waste ground. 0-420 m (Ingleborough, Mid-W. Yorks.).
