Description




Our premium blue cornflower seeds deliver reliable germination rate and upright slender branching growth habit. Botanically named Centaurea cyanus, also called Bachelor’s Button, it is a classic European rustic wildflower. It bears unique cornflower-shaped vivid deep blue double blooms with serrated bracts, paired with narrow gray-green foliage, presenting elegant pastoral temperament.
Blue cornflower features excellent cold resistance and strong tolerance to barren sandy soil, adapting well to harsh growing conditions. It blooms non-stop from late spring to early autumn. Widely used for wildflower meadow mixed seeding, cottage garden border backdrop, roadside ecological green belts, slope greening and fresh cut flower arrangements with long vase life. It thrives in loose well-drained ordinary garden soil with little fertilizer demand. Only occasional watering during prolonged drought and regular weeding are needed, and it has strong self-seeding ability for natural annual renewal, ideal for ecological landscape construction and novice gardening enthusiasts.

Planting Instructions

  1. Soil Preparation: Select loose, breathable, well-drained loam or sandy soil, avoid heavy clay and waterlogged low land to prevent root rot and seedling damping off.
  2. Sowing Method: Sow seeds evenly on level soil surface, cover with 0.5cm thin soil layer and gently compact. Warm water soaking for 8 hours helps break dormancy and raise germination rate.
  3. Germination Condition: Keep topsoil slightly moist without stagnant water, constant temperature 15–22°C, seeds germinate within 7–14 days.
  4. Seedling Care: Thin overcrowded seedlings for proper spacing; full sunlight strengthens stalks and increases flower quantity, prevents leggy growth.
  5. Daily Maintenance: Water deeply only during long dry periods; remove faded flower heads if self-seeding is not required; prop up tall branches in windy areas to avoid lodging.
