Delphinium carolinianum, or blue larkspur, is a wild delphinium native to the prairies of the Midwest. Cold-hardy to zone 4, its range is widespread, from the edge of the American West to the Southeast. Light blue blooms rise on one-to-three-foot stems above blue-green, lobed leaves, creating waves of blue in open meadows in early spring through summer.

Straight species delphinium are less available than those of European and Asian origin. Delphinium elatum is bred for its reliable bloom, range of colors, height, and performance in the landscape. The plant is available in tall and dwarf varieties, and colors ranging from marine blue to rose pink to clear white. D. elatum produces beautiful flowers, attracts pollinators to the garden, and resists mildew diseases.

Delphinium grows best in cool climates. In warm climates, plants die back in the summer heat and are treated as annuals. Tall varieties may require staking and benefit from deadheading the spent blooms. Delphinium needs moist and very well-drained soils; they may get crown rot and mildew if conditions are too moist.  Full sun conditions stave off powdery mildew.
