An absolute cottage garden classic. Plant Delphiniums in bold clumps for back-of-the-border impact. Delphinium 'Black Knight' is an extra special variety with some of the deepest indigo-blue flowers, each with a black eye.
The sight of Delphiniums in a garden is simply divine. They flower from early summer, and will often flower twice. The plants are architectural and handsome, you certainly won't regret planting these handsome perennials! Height: 1.7m (5.5'). Spread: 75cm (29").
Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.
