Delphinium exaltatum
Tall Larkspur
Delphinium exaltatum produces masses of purple blue flowers which appear in early to mid-summer on branched flower stems. Leaves are deeply divided. Cut back for secondary autumn bloom. Great addition to woodland edge or savannas. Care should be exercised when handling all Delphiniums as they are toxic to humans and livestock.

Planting young plants
From Early Spring TO Mid Spring
Delphiniums are very difficult to grow from seed. Buy as a potted plant at the nursery. Plant in the spring. Prepare the soil, mixing in 2 to 4 inches of compost. Dig a hole twice the diameter of the plant’s container. When planting, ensure that the top of the root ball is level with the soil. Insert supports no later than midspring or when the plants reach 12 inches high. Stake the low-growing perennials with twiggy, brushwood support. The taller, large-flowered delphiniums need sturdy stakes.
Flowering Season
From Early Summer TO Late Summer
Delphiniums are perennials grown for their showy spikes of colorful summer flowers in gorgeous shades.
Propagating by cuttings
From Early Spring TO Mid Spring
Take Basal cuttings when young emerging shoots have two or three pairs of leaves, take a thin portion of parent tuber or root material with the shoot
