Annual – blooms quickly in the first growing season but must be replanted the following year. 48" tall. Rocket Larkspur Lilac Spire is a fantastic cut flower and the tall, spiky blooms add texture and soft color to any summer bouquet. To promote multiple blooms on one plant, after the first flower is spent (or cut), make sure to cut the plants back almost to the ground. This low-maintenance annual is a quick, vigorous grower in any sunny to partially-sunny spot with well-draining soil. If blooms become heavy or if there is consistent rainfall, staking may be necessary. Plant seed in the fall for earlier blooms or sprinkle seed on bare soil in the spring once all chance of frost has passed.
