Delphiniums bear tall upright spikes laden with intensely-coloured flowers. They're a traditional staple of cottage garden schemes, providing height and a touch of drama to ornamental borders. The flowers are loved by bees and are superb for cutting.
Delphinium 'Blue Lagoon' bears long spikes of semi-double blue flowers with a white 'eye'. It makes a dramatic, mixed display, and a fantastic cut flower. It's ideal for growing towards the back of a sunny border.
For best results grow Delphinium 'Blue Lagoon' in moist but well-drained soil in full sun. Although their 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.
