From DamavandPro, these Giant Larkspur Delphinium consolida (syn. Consolida ajacis) Imperial Mixed seeds bring tall, spire-like blooms to borders and cutting gardens. A hardy annual associated with classic cottage-garden planting, it’s chosen for its architectural presence and a mixed palette of deep blues, soft pinks, pure whites and lilac-purple tones—ideal for adding height through the back of beds or for harvesting into fresh and dried arrangements.
Sow directly outdoors in March–May or September for earlier blooms the following year. For improved germination, the seeds benefit from a short cold stratification: place the seed packet in the fridge for 1–2 weeks before sowing. Choose a full sun position with well-drained, fertile soil, and be prepared to stake or net plants in exposed or windy spots. Seedlings typically emerge within 14–21 days.
Height: typically 90–120 cm
For the longest-lasting cut flowers, harvest when the bottom third of the florets have just opened. Remove the central flower spike as it begins to fade to encourage a second flush of smaller blooms.
