 Full Description

Scarlet Spire Larkspur (Delphinium consolida ‘Scarlet Spire’) is a striking annual wildflower producing tall, elegant flower spikes covered in vivid scarlet-red blooms. A classic cottage garden favorite, this larkspur adds strong vertical interest to flower beds, borders, and wildflower plantings. The finely cut, feathery foliage creates a soft texture that contrasts beautifully with the bold flower spikes.

Scarlet Spire is highly attractive to bees, butterflies, and other beneficial pollinators. It is also excellent as a cut flower, with long-lasting blooms that bring height and color to floral arrangements.

This variety is fast-growing, easy to cultivate from seed, and thrives in cooler spring conditions, making it ideal for early-season colour.

 Growing Information (from seed)

Sowing:

  • Direct sow outdoors in early spring as soon as soil can be worked
  • Can also be fall-sown in mild climates for earlier spring blooms
  • Does not transplant well – direct sowing is recommended

Soil:

  • Well-draining soil is essential
  • Prefers moderately fertile soil
  • Avoid heavy, waterlogged soils

Planting Depth:

  • Sow seeds on the surface or lightly cover with 2–3 mm of soil
  • Seeds need light to germinate

Spacing:

  • Space plants 20–30 cm (8–12 inches) apart

Watering:

  • Keep soil evenly moist during germination
  • Once established, moderate watering is sufficient
  • Avoid overwatering

Germination:

  • 10–20 days under cool conditions

 Care:

  • Remove spent flowers to encourage extended blooming
  • Tall plants may benefit from light staking in windy areas
  • Low maintenance once established

Bloom Time:

  • Late spring to mid-summer

Height:

  • Approximately 60–100 cm (2–3 feet)

Stratification:

Not required, but cold stratification improves germination.

Optional method:

  • Place seeds in moist paper towel inside a sealed bag
  • Refrigerate for 7–14 days before sowing

This mimics natural winter conditions and can increase germination rates. 

Medicinal Properties: Larkspur species are not used medicinally and are considered toxic. 

Historically, larkspur was used externally as a natural insect repellent, but all parts of the plant are poisonous if ingested, to both humans and animals. It should be grown strictly as an ornamental flower.
