A pretty Pyrenean perennial with flat rosettes of hairy ovate wrinkled leaves and flattish purple flowers in May and June, on stalks about 4 in. high. There is also a white-flowered variety. Other species are Heldreichi, and serbica, yellow. They are excellent rock plants, requiring peaty soil, and may be increased from seeds and by division. New plants may also be obtained from leaf cuttings inserted in leaf mould or sandy peat in a close frame.
