Delphinium

Looking like something out of a storybook, delphiniums are the favorite flowers of many gardeners. They produce luxurious, gravity-defying flower spikes of blue, pink, white, or purple flowers, which tower above substantial mounds of coarse leaves

Plants perform best in cool summer climates with little wind and adequate moisture. They may rebloom if flower stalks are cut back after flowers fade.

Joe Pye weed

Lofty Joe pye weed fills in the back of the border after delphiniums finish blooming, so it makes great backdrop for them.

Hyssop

Anise hyssop also makes a good backdrop for delphiniums. Its purple-blue blooms form after delphinium is done blooming, and the delphinium foliage covers the bare base of anise hyssop.

Salvia

Purple perennial salvia coordinates beautifully, and its spires echo the towers of delphinium blooms, but on a smaller scale.
