a genus of stemless perennial herbaceous plants of the family Primulaceae. The plants form a tuberous rhizome and a rosette of long-petioled, rounded-reniform leaves. The drooping flowers are solitary and on long pedicels; their coloration is white, pink, and red. There are more than 20 species (according to other data, about 55), distributed in the Mediterranean region and Southwest Asia. The USSR has six or seven species, growing in the Crimea and the Caucasus. The plants grow in mountain forests and in shrubbery thickets.
Commonly cultivated are varieties and hybrids of the large-flowered C. persicum. One of the best houseplants, it blossoms from October through March. After flowering the leaves die off, and the plants become dormant. The plant begins to grow again at the end of May, at which time transplantation is necessary. Propagation is by seeds, which are sown in hothouses in July and August. Seedlings are transplanted several times, first into boxes and then into pots. With proper care (sufficient light, moderate temperatures, regular but not excessive watering) the plants are long-lived, sometimes living more than 20 years. C. europeum, which has small aromatic flowers, is also grown as a houseplant. C. coum and C. vernum are grown in the open ground.
