Candle Light Blue Shades Delphinium is a new F1 hybrid bred for superior uniformity and reliability. This delphinium reaches its full potential in 105-125 days, producing tall spikes of blue flowers that command attention in any garden or vase. Hardy from zones 3-7, it thrives in partial shade and grows as a compact bush, reaching maturity at a manageable 12 inches of spacing. This variety excels as a cut flower, with blooms that open gradually along the stem and rebloom in late summer if cut back immediately after the first flush.

The hybrid vigor of this delphinium shows in its exceptional uniformity and performance across growing conditions. Blue spikes open gradually from base to tip, extending the vase life and visual impact of each cutting. Cut back immediately after flowering and you'll be rewarded with a second bloom cycle in late summer and early fall, a rare trait that makes this variety genuinely rewarding to grow season after season.
This delphinium shines as a cut flower. The blue spikes are prized for wedding arrangements, garden displays, and floral design work. When cut with about one-third of the flowers already open along the stem, it places immediately in water and continues opening gradually, extending vase life significantly. The rebloom capacity makes it particularly valuable for cut flower production or for gardeners who want multiple harvests from a single planting.
No timeline data available yet for this variety.
Sow seeds 10-16 weeks before your planned outdoor planting date. Cover seed lightly and germinate at cool temperatures. Transplant seedlings into larger cell packs or 3-4 inch containers 6-8 weeks after germination, continuing to grow them at 50-55°F (18-21°C) in a greenhouse or cold frame.
Harden off seedlings gradually over 7-10 days, then transplant outside after the last frost has passed. Space plants 12 inches apart. For greenhouse production, transplant plugs into a raised bed in August through September to establish strong root systems before winter.
Harvest when approximately one-third to one-half of the flowers on the stem are open. Cut in the early morning when stems are fully hydrated. Place immediately in clean water to maximize vase life. The gradual opening of remaining buds along the stem extends the display for several days after cutting.
Cut back immediately after the first bloom cycle fades to encourage the second bloom in late summer and early fall. This prompt removal of spent flowers redirects the plant's energy into new flower production rather than seed development.
