CYCLAMEN: 

Colorful perennials that bloom all winter. They are shade lovers and love cool to cold weather. Most species die or go dormant when weather gets hot. Native to the Mediterranean. Tubers should be planted just below the soil surface. Best in slightly alkaline soil, prefer light to medium shade when blooming and deep shade when dormant. Species will reseed themselves. Keep soil evenly moist but over-watering will kill them.
