Notes: Larkspur is known for its tall spikes of colorful, tubular flowers, which come in shades of blue, purple, pink, white, and red. It's popular for cottage gardens, cut flower gardens, and floral arrangements. Larkspur is easy to grow in cool to temperate climates and prefers moist, well-drained soil. Although it is relatively low-maintenance, it benefits from regular deadheading to encourage more blooms. Due to its toxicity, care should be taken to keep it away from pets and small children.
Years ago, I would grow white Larkspurs for cut flowers. They are beautiful when displayed in an antique looking vase!
