Delphinium ‘Black Knight’

No cottage garden is complete without drifts of statuesque Delphiniums! Delphinium ‘Black Knight’ produces upright spires of indigo-blue flowers in June and July, and will often flower again in late summer. Simply stunning for adding height to sunny herbaceous borders, Delphinium flowers are also excellent for cutting for a vase indoors. The blooms are also attractive to bees and other pollinating insects. Height: 1.7m (5.5′). Spread: 75cm (30).
