Cornflower Wildflower – JC1438

Striking blue annual wildflower for pollinator-friendly meadows, field margins, and ornamental borders. Quick to establish and low-maintenance.

Cornflower (Centaurea cyanus) Wildflower (JC1438) is a striking annual wildflower known for its vibrant blue blooms and long flowering season. Highly attractive to pollinators such as bees and butterflies, Cornflower adds both ecological value and visual interest to landscapes.

This versatile species is ideal for field margins, wildflower meadows, BNG schemes, parks, gardens, and ornamental borders. Quick to establish and low-maintenance, Cornflower provides bold seasonal colour while supporting biodiversity in both urban and rural environments.

  • Seedbed Preparation: Prepare a fine, firm seedbed free from weeds. Ensure good seed-to-soil contact for optimal germination.
  • Sowing Time: Best sown in spring or early autumn when soil moisture is consistent.
  • Sowing Rate: Broadcast evenly over the prepared area. Lightly firm to optimise germination but avoid burying seeds deeply.
  • Establishment: Cornflower germinates quickly, producing bright blue flowers in the first season.
  • Management: Minimal maintenance required. Allow self-seeding to maintain naturalised displays.
  • Long-Term Care: Re-sowing is required annually to maintain continuous colour. Avoid high-fertility soils.
