EXCLUSIVE - Blue Mirror delphinium has fine textured foliage literally covered in sprays of intensely ultramarine blue little trumpet-shaped florets. The compact lacy plants make a lovely display in the garden and for bouquets. First introduced to England in 1818, this easy-care beauty is known in its native land of China as “Herb of the Flying Swallow.” While it’s well known that hummingbirds zero in on red, they also love true blues like this one for supplies of sweet nectar.
