USDA Zone: 3-10
The AURORA series of Delphinium offers excellent uniformity and hybrid vigor with flowers tightly packed on sturdy stems. They form stately spires of flowers in early summer, over a mound of deeply-cut green leaves. This selection features tall spires of vivid blue, semi-double flowers each with a white bee or centre. Excellent for cutting. Trim back spent stems to the base to encourage repeat bloom later in the autumn. Be on the watch for aphids, slugs and powdery mildew, all common problems with Delphiniums. Staking the individual flower stems in June as they begin to elongate is wise, to help avoid wind damage.
