Growing Giant Imperial Mix Larkspur in the Flower Garden

For the earliest blooms, direct sow larkspur in early spring as soon as the soil can be worked, planting 0.25 inch deep. In mild-winter climates, fall sowing can overwinter to produce earlier spring flowers. Keep soil lightly moist through germination, which can take 14 to 21 days in cool conditions.

Thin or transplant seedlings to 6 to 10 inches apart in full sun to partial shade. Provide steady moisture during rapid growth, and stake plants in windy sites to keep tall stems straight for cutting. Deadhead spent spikes to keep plantings tidy.

Harvesting of Giant Imperial Mix Larkspur

Harvest spikes for fresh bouquets when about one-third of the florets are open. For drying, cut when the color is strong, then hang the stems upside down in a dark, well-ventilated place to preserve the bloom color.

About Giant Imperial Mix Larkspur Garden Seeds

Giant Imperial Mix is a classic larkspur blend grown for tall, colorful flower spikes and fine, ferny foliage. It is an easy cool-season annual for borders and cutting gardens, and it holds color especially well when dried.

Use it as a backdrop planting in beds, along fences, or in mixed spring bouquets where height and saturated color are needed. This species is noted for its ability to reseed easily if the location is suitable. An established bed of larkspur will often come back year after year if allowed to reseed.

Tips From Our Gardeners

Sow early and keep plants cool for the strongest stems. A light mulch helps even out soil moisture, and a simple stake or netting keeps tall spikes upright through spring winds.
