Blue Mirror Delphinium
Delphinium grandiflorum ‘Blue Mirror’
Plant Height: 12-18 inches
Spacing: 10-12 inches
Hardiness Zone: 3-7
Very different from the traditional tall spiky Delphiniums, this strain forms a low, bushy mound of lacy green leaves. Plants bear loose sprays of single electric-blue flowers throughout the summer. Ideal for containers, the rock garden and for edging the sunny border.
