Delphiniums are one of the classic flowers of the traditional summer garden. Their tall upright spikes laden with intensely-coloured flowers are a feature of herbaceous borders, where they are best grown near the back to add height and drama. The plants look best grown in a group with several other varieties in shades of blue and cream. Although the flowering season is quite short, delphiniums can often be coaxed into producing a few later flowers if the flower spikes are cut down as soon as the blooms are over. Black Knight Group produces gorgeous deep purple flowers with black eyes.
