Laser Beam™ Delphinium (also known as Laser Beam™ Larkspur) is a perennial with upright flower spikes covered in rich blue blooms during the summer. Its strong stems support full florets for an impressive floral display in garden beds and borders. Delphinium x ‘Holtlabea812’ USPP36982 delivers eye-catching color and architectural interest in perennial landscapes.
This perennial is ideal for borders, mixed beds, and cutting gardens where strong summer color and vertical form are desired. Plant Laser Beam™ in groups for a bold effect or allow individual plants to stand out with their striking spires.
Laser Beam™ Delphinium Care
Plant Laser Beam™ Delphinium in full sun (at least 6 hours of direct sunlight per day) to support abundant flowering. Provide well-drained soil and water regularly while the plant becomes established, then maintain consistent moisture during hot or dry spells to support bloom production throughout the season.
Laser Beam™ Delphinium Spacing
Once established, Laser Beam™ Delphinium typically reaches about 24–30 inches tall and 14–16 inches wide. Space plants approximately 14–16 inches apart for mass plantings or hedges, or give each plant room to showcase its natural upright form in mixed perennial beds.
