Choosing Zone 6 Flowers for Your Garden

When selecting zone 6 flowers, hardiness is only the starting point. Also consider sunlight, soil moisture, bloom time, mature size, and how each plant will fit into the surrounding landscape.

Perennials can help create a zone 6 flower garden that returns with fresh color and texture from year to year. Browse our perennial plants to compare options for beds, borders, and mixed plantings.

The USDA Plant Hardiness Zone Map is designed to help gardeners estimate which perennial plants are most likely to survive winter in a given location, but individual growing requirements still matter.
