25 Frost-Tolerant Winter Plants

Snowdrop galanthus flowerIf you live in a cold but mild hardiness zone (Zone 6, for example), you can keep many of the following 25 stunning plants in containers outdoors during the winter. Container gardeners in colder climates can also keep hardy winter plants, but the selection is more limited.
