Tall Larkspur Seeds
Delphinium exaltatum
- HOW TO GROW
- FAST FACTS
HOW TO GROW
Sowing: Direct sow tall larkspur seeds in late fall, planting just below the surface of rich soil. To plant in the spring, mix Delphinium Exaltatum seeds with moist sand and store them in the refrigerator for 60 days before direct sowing. This seed can also be planted indoors on the surface of a flat, and kept evenly moist and at a temperature of 60-65 degrees F until germination. Transplant seedlings after the last chance of frost.
Growing: Water the plants occasionally, especially in periods of dry weather. Avoid overwatering, since good drainage produces the healthiest growth. Keep weeds down, since this plant does not like competition. Remove wilted blossoms for the best blooming; if blooming decreases, the entire plant can be cut back for new growth and possible second blooming. If the flowers are left to mature, they will readily reseed. This plant attracts hummingbirds and butterflies and resists deer.
Harvesting: For fresh flowers, cut the stems near the ground and place them in water immediately; strip the leaves that will fall below the water. Handle these plants with care, since the seeds and leaves contain poison.
Seed Saving: After the flowers fade, this plant will produce papery light brown seed pods that open at the top when ripe. Mature seed will be a dark brown color. Remove entire stalks of ripe seed pods and spread them out to dry. Alternatively, the plants can be shaken over a container to remove the seed from the open pods. Store the cleaned tall larkspur seeds in a cool, dry place.
