Larkspur (Delphinium Consolida Lilac Spire) - Transform your landscape by sowing Larkspur seeds! One stand of these Larkspur Delphinium Consolida plants against a fence or toward the back of the flower garden creates a breathtaking sight. Larkspur are loaded with big, fully double blooms, and they are also vigorous, blooming quickly from flower seed. Larkspur give weeks of color as they bloom from the bottom of the spike up, so the top is still in bud while the bottom is in full bloom. This lilac Larkspur flower is also lovely in the vase.
To aid in the germination of Larkspur seeds, place the flower seeds on a damp paper towel, seal the towel and seeds in a ziploc bag and place in the refrigerator for 1 - 2 weeks. After removing the flower seeds from the refrigerator, directly sow the Larkspur flower seeds outdoors in prepared soil, keeping the seeds moist until germination. Larkspur flower seeds can also be sown indoors and Larkspur seedlings transplanted outside after 8 weeks of growth. Larkspur care includes staking the tall flowers if needed, watering deeply each week, and applying a liquid fertilizer every other week during the growing season. After blooms are spent, cut back hard to encourage a second bloom later in the season. The flower seeds and Larkspur plants are poisonous so do not consume.
