Description

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.

How to Grow
When growing Delphiniums, choose a sunny position that is sheltered from strong winds, on moist, well drained soil. Protect young delphinium plants from slugs and snails.
More Info
Feed and water delphinium plants until they are fully established. The tall stems of delphinium flowers will require staking with stout canes. Canes should be put in place by mid spring to ensure that the plants are adequately supported throughout the growing season. Cut spikes of faded delphinium flowers back to a flowering side-shoot to encourage a second flush of blooms to be produced. In autumn, cut the old foliage back to ground level. Caution: irritant to skin and eyes, harmful if eaten.
