A large ornamental okra with dinner-plate-sized, sulfur yellow flowers with dark eyes. Each flower lasts only a day—unfolding slowly in the morning and closing gradually in the evening—but the abundance of flowers open on any one day conceals their short life span.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Agastache ‘Summer Breeze’ produces hundreds of 1.5-inch-long translucent, tubular blossoms. The flowers are painted in luscious sunset shades and appear from late spring to frost. In hot weather, peach, champagne, and soft pink are its colors, while in cooler months the flowers darken to pale copper and medium rose.

This early, compact bloomer grows to only about 6 or 7 inches tall. With its icy blue-purple flowers, it works well when planted tightly along the foreground of a bed. Its color blends easily with most other hues and textures. -Julia Jones, Designing with annueals, Fine Gardening issue #120
