Botanical Description

Densely colony-forming to 1m across. Leaves about 8cm wide, sometimes much larger, divided into seven diamond-shaped lobes, each further and bluntly or sharply divided and toothed; aromatic and slightly sticky. Flowers in fairly compact heads on long peduncles, about 2.5cm across, in shades of purplish-pink, the stamens with purplish filaments and orange-red anthers. There is a near-white form in which the flower-stalks and calyces are red, contrasting well with the flowers. A variable plant, in size and colour, with several cultivar names: the more robust forms require careful placing to avoid smothering smaller plants. Widespread but only locally common and sometimes naturalised (including Britain). Southern Alps, Apennines, Carpathians, Balkan Peninsula. Too vigorous and spreading for the rock garden.
