No cottage garden is complete without drifts of statuesque Delphiniums! Delphinium ' Black Knight' produces upright spires of indigo-blue flowers in June & July, & 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 & other pollinating insects.
