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.

I think your team is great, and you have taught me well. I have been gardening now for 3 years still learning, My best gardener is Geoff Hamilton, I find a lot of inspartion from him.
I have recently discovered this plant and I am now learning how to protect it over winter. Your instructions are very clear and helpful.
