Delphinium Larkspur (Blues)
Plant in raised beds in Spring & Autumn. Space each delphinium ½ m2 to 1 m2 apart. Wide spacing helps control height; with close spacing plants will grow taller.
Full sun preferred but successful in up to 50% shade. Delphiniums are very hardy and tolerant of frosts. They will stand and even benefit from winter freezing. Permeable shelter (tall loose shrubs or small trees) is required. Soil must be rich as delphinium and well drained, particularly in warm areas. Delphiniums must not get warm or very wet feet.
