These are pretty little Alpine plants, 3-6 in. high, closely related to the Primulas, and chiefly valued as rock plants. They like a well-drained soil of sandy loam and peat, and are increased by seeds or cuttings. The best-known kinds are: A. alpina, purple rose; A. carnea, pink with yellow eye; A. Chamoejasme, white to pink; A. lanuginosa, pink with yellow eye; A. pyrenaica, white, yellow eye; A. sarmentosa, rose, yellow eye; but there are many others.
