Delphinium 'Black Knight'
Part of the Pacific Giants group of Delphiniums. This selection features dark purple almost black flowers with dark centres growing to 180cm. Plants form a low mound of deeply-cut green leaves, bearing tall spikes of satiny flowers. These clump forming perennials are the stars of the early summer border. Delphiniums prefers a full sun position in well drained soil and grow best with some shelter from wind.
Excellent cut flowers.
