The Persian Cyclamen is dealt with in the next section. The hardy kinds have become popular of late years for rock gardens, cold greenhouses, etc. They are easily grown in shady or chalky loam, and are raised from seeds and by division of the tubers. Of the many kinds known these are among the best: africanum; Atkinsi, with several varieties; cilicicum; Coum; europoeum; ibericum; neapoli-tanum (hedercefolium); repandum; etc. The twisted flowers are mostly purple in colour, but there are several white forms, and with few exceptions the roundish leaves are beautifully marbled and veined.
