USDA Plant Hardiness Zones

To help gardeners understand which plants will grow well for them, the entire USA has been segmented into ‘Plant Hardiness Zones’. Knowing your zone number is helpful when shopping for plants because:

  • Cold-area gardeners can avoid buying plants that simply won’t survive their lowest winter temperatures.
  • Warm-area gardeners can steer clear of plants that need a period of cold weather in order to bloom again.

Savor Delphinium's gorgeous blooms in the garden and in bouquets

A cottage garden favorite, Delphiniums boast spikes of brightly colored flowers in cool colors. The plants form mounds of dark green, glossy foliage topped in early summer by the dramatic, spurred flowers that are perfect for bouquets. Taller varieties form an incredible backdrop for perennial plantings and all types look at home in both formal and informal beds. Plant them in full sun in an area sheltered from strong winds.
