The Giants' Dance Delphinium Collection

Plant them in spring after the last frost. Plant in a sunny site in fresh, rich, and well-drained soil. Leave at least two or three shoots on young plants and five to seven on well-established delphiniums. During growth, water once or twice a week and apply liquid fertiliser every two or three weeks. Remove faded flowers by cutting the spikes at the level of the small flowering side shoots. Cut back the entire plant to ground level in autumn. Tip: Embrace height with these giant plants that structure and balance volumes in the garden. The tallest ones, when isolated, will add volume and lightness against a dark backdrop of hedges or conifers. Those of intermediate size will adorn tall flower beds, such as those with giant dahlias. Take care to maintain the vegetation with regular watering. Keep an eye out for slugs.
