Larkspur (Delphinium Consolida Rocket) - Larkspur Rocket is an annual flower grown from wildflower seed. It normally grows between 24 - 36 inches tall depending on soil fertility and moisture. It usually has 2 - 3 forking stems which are branched. The leaves alternate and are 3 inches across, and they have a lacy appearance. The lovely 1 inch blooms come in a mix of colors: white, lilac, and pink. What a spectacular color display for the wild flower meadow, and they are so easy to establish from Larkspur wildflower seed.
Rocket Larkspur Delphinium blooms during the summer and lasts about 1 - 2 months. Each flower is replaced by a pod containing numerous small black wild flower seeds, and they are easily dispersed by gusts of wind. Larkspur, like many wild flowers, can re-seed itself if wild flower seed is allowed to drop on the ground. Seed will lay dormant until temperatures and moisture are sufficient to cause germination.
To aid in the germination of Rocket Larkspur seeds, place the wildflower 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 seeds outdoors in prepared soil, keeping the seeds moist until germination. Larkspur care includes cutting the plants back hard after blooms are spent. This will encourage a second bloom later in the season. The wildflower seeds and Rocket Larkspur plants are poisonous so do not consume.
