Plant Name: Larkspur, Rocket Mix Latin Name: Consolida ajacis, Delphinium ajacis, Consolida ambigua, Delphinium ambiguum Days to Germinate: 14-28 Days to Bloom: 110 Plant Height: 2 - 4 Feet Spread: 10 - 24 Inches Bloom Diameter: 6 - 18 Inches Growth Habit: Upright USDA Zones: 1-11 Lifespan: Annual Brand: TomorrowSeeds Sunlight: Full Sun, Partial Shade Pollination: Heirloom, Open-Pollinated GMO: No Fungicide-Treated Seeds*: No Seeds Packed For**: 2026 *Fungicide-treated seeds protect the seedlings from diseases until they are up and growing. Do not eat treated seeds. **Seeds are freshly packed for the growing season of the year listed. Seeds are still viable beyond pack date. Store in a cool and dry location such as the refrigerator or basement to best preserve germination rates. Planting Instructions: Soil Preparation: Choose an area with heavy, well-draining soil that receives at least 6 hours of sunlight each day. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 6-8 inches deep. Loosening the soil will help the plant establish strong roots. If the soil is heavy or clay-like, mix in some sand or compost to improve drainage. Optionally, form rows of soil beds 4-6 inches high and at least 2 feet apart. This formation of ridges will help with drainage, ensure good airflow, and make harvesting for cut flowers easier. Lay down 1/2"-3/4" peat moss, sawdust, or potting soil, the soil surface. This layer is beneficial for flower seeds because it can the improve the germination environment and prevent soil crusting. Planting: Larkspur requires cold temperatures to germinate properly. Starting Indoors: For earlier blooms,vernalize seeds by chilling seeds at 35F for 7-14 days for best germination then start planting indoors in containers 6 weeks before the last expected frost date in Spring, keeping seedlings 45F-55F. Harden off then transplant seedlings outdoors when temperatures are consistently 50F. To transplant seedlings, prepare a transplant hole outdoors in a sunny location. Remove the plants carefully from the pots or flats and set them in the transplant holes, burying some of the stem in the ground. Pack the soil loosely around the plant and leave a slightly sunken area around each plant to hold water. Water the plants after transplanting. Directly Sowing: If directly sowing outdoors, plant Larkspur after the first hard frost in early spring to cold-stratify seeds. Plants will germinate in late Spring when the soil warms to at least 50F. For fall planting, sow 6-8 weeks before the first expected frost and allow roots to establish over winter for early spring growth. If winters are harsh, mulch lightly to protect young seedlings. For blooms in late Spring of the following year, sow outdoors after the first hard frost in Fall to cold-stratify seeds. To plant, make holes 1/8 inch deep and spaced 6-12 inches apart down the rows of raised beds. Plant 2-3 seeds per hole, then cover thinly with soil. In small plots, flower seeds may be scattered and gently watered in. Once seedlings emerge, plants can be separated and spaced 6-12 inches apart to allow room for mature plants to spread and prevent overcrowding. Water after planting. Planting Depth: 1/8 inch Within-Row Spacing: 6-12 inches Between-Row Spacing: 12-18 feet Care During the Season: Larkspur requires minimal care once established. Water regularly, especially during dry spells. Deadhead spent flowers to encourage longer blooming periods and prevent self-seeding, unless you want the plants to reseed themselves. Thin out crowded seedlings early in the season to allow ample space for growth.
