Description and Characteristics
Delphinium cultorum ‘Dasante Blue’ is a compact, elegant hybrid delphinium celebrated for its deep violet-blue semi-double flowers and manageable height, making it an excellent choice for smaller gardens, containers, and mid-border displays. This cultivar belongs to a group of dwarf or mid-sized delphiniums, bred for tidy growth habits, strong stems, and fewer staking requirements.
The flowering spikes are densely packed with richly coloured blooms, each with a soft sheen and occasionally a light central “bee.” Blooms typically appear in early to midsummer, with a second flush possible in late summer if cut back promptly.
Reaching around 50–70 cm in height and 30–40 cm in spread, Delphinium ‘Dasante Blue’ forms a neat mound of deep green, deeply lobed foliage. Its striking colour, uniform flowering, and moderate size make it ideal for both traditional and modern gardens.
