Delphiniums are grown for their showy flowers carried in spikes or racemes. They are grown as garden plants as well as commercially as cut flowers. Most delphinium hybrids and cultivars are derived from D. elatum. Other hybrid crosses have included D. bruninianum, D. cardinale, D. cheilanthum, and D. formosum. The main flowering stems are erect and vary greatly in size between species, from 10 cm in some alpine species, up to 2m tall in larger meadow-land species.
