description_en: Genus of about 19 species of tuberous perennials found in habitats ranging from alpine woodland and damp woods to dry sands and maquis, from the Mediterranean east to Iran and south to Somalia. Leaves are rounded to heart-shaped, sometimes toothed or lobed, often with silver zones or light and dark patterns above, and purplish red below. Leaves of autumn-flowering species last through winter to spring. The nodding, sometimes fragrant flowers, 1-3cm (1/2-1 1/4in) long, each have 5 reflexed, twisted petals, varying from white to pink and carmine-red, often with darker "mouths" (perianth tube rims). Flowers may be borne at almost any time of year, depending on the species. In most species, the flower-stalk coils on to the soil surface after flowering to release the ripe seeds. C. persicum has been selected extensively to produce a wide colour and size range, the flowers often much larger than those of the wild species. Grow fully hardy species and cultivars in a rock garden, border, or raised bed. Frost-hardy to frost-tender cyclamens (with the exception of C. parviflorum), need a warm, dry summer dormancy; outside Mediterranean climates, they are best grown in a cool greenhouse, alpine house, or bulb frame. Cultivars of C. persicum are excellent in a conservatory or as houseplants. All parts may cause severe discomfort if ingested.

hardiness_en: Fully hardy to frost tender.

cultivation_en:

propagation_en: Sow seed as soon as ripe, in darkness, at 6-12°C (43-54°F). Sow seed of C. persicum at 12-15°C (54-59°F): sow seed of open-pollinated cultivars in late summer to flower in about 14 months; sow seed of other cultivars from late winter to mid-spring to flower in autumn of the same year. Before sowing, soak all seed in water for at least 10 hours and rinse thoroughly.

pests_en: Mice or squirrels may be a problem. Prone to red spider mites, vine weevil, cyclamen mite, and grey mould (Botrytis) under glass.
