Delphiniums are the stars of the early summer border. Plants form a low mound of deeply-cut green leaves, bearing tall spikes of satiny flowers. This selection has deep midnight violet blossoms, the darkest available. Removing faded spikes at the base will encourage repeat blooming in fall. Plants can be prone to mildew in mid summer; simply cut back hard to encourage fresh foliage. Use a high phosphorous fertiliser each year, in early spring to prevent this and encourage prolific flowering.
