This genus contains around 250 species of annuals and perennials native to mainly temperate zones in the Northern Hemisphere, and belongs to the widely cultivated buttercup family (Ranunculaceae). The light to bright green leaves are usually hand-shaped and slightly hairy. Delphiniums are generally thought to have tall erect flower stems but many species have short branching ones. All species, however, grow striking flowers along much of the length of the stem. Characteristic flower colors include blue and deep pruple, though some species have white, red, or pale green flowers. Delphinium comes from the Greek delphin (dolphin) and describes the shape of the nectar-containing spurs found at the base of the flower.
CULTIVATION
Plant in full sun with moist, fertile, well-drained soil. Any withered foliage must be cut back to maintain the vigorous growth of the plant. Annuals and species can be propagated from seed, whereas hybrids and cultivars can be propagated by division or from cuttings.
Top Tip
There cannot be many plants more suited to a border of feature bed than delphininums and, in particular, D.elatum is a perfect choice. Stake, if necessary, for extra support.
