Plant description

Spikes of dark purple flowers with black centres. Stately spires of semi-double, deep purple flowers, opening in June and July on tall stems. These dark-eyed delphiniums look fantastic planted in bold clumps as part of a cottage-garden scheme or towards the back of a well-drained, sunny border, where they will add height and bold splashes of colour. They also make excellent cut flowers.

Care guide

Protect young foliage against slug and snail damage in spring. Stake with bamboo canes in mid-spring, before the flowers appear. During the growing season, apply a balanced liquid fertiliser every 2-3 weeks and wearing gloves cut back the faded flower-stems to a flowering side-shoot to encourage repeat flowering. At the end of autumn cut back and compost the faded flower stems.
