Centaurea cyanus 'Blue Boy BIO' – Organic blue cut flower for field and cut bouquets

Centaurea cyanus 'Blue Boy BIO' is the organic version of the popular blue cornflower, specially grown without chemical fertilizers or pesticides. This intense blue cut flower combines the natural character of wild cornflowers with professional cut flower cultivation, making it ideal for organic horticulture, sustainable flower production, and creative florists who consciously choose ecologically responsible flowers.

The combination of bright blue flowers, long, sturdy stems, and organic cultivation makes Blue Boy BIO a sustainable and attractive choice for both fresh bouquets and dried flower arrangements.

Intense blue flowers with a natural look

Blue Boy BIO has bright blue, open flower heads that form an airy rosette. The flowers have a natural, wild look, making them perfect for:

• field and picking bouquets

• organic and sustainable flower creations

• bridal work and ceremonies with fresh, natural tones

• botanical styling for hotels and events

The intense blue color adds a vibrant and fresh touch to bouquets and creates a beautiful contrast with white, pink, or yellow flowers. Thanks to the organic production process, the flowers have an authentic, pure character that customers appreciate.

Strong, long stems for professional cut flower cultivation

Centaurea cyanus 'Blue Boy BIO' develops long, straight stems of 60–90 cm, depending on location and care. The stems are robust and suitable for transport and use in fresh bouquets.

Thanks to its branching growth habit, the plant produces multiple harvestable stems per season, making it viable for both small florists and commercial organic growers.

Long vase life and versatile applications

The flowers have an average vase life of 7–10 days, especially when cut in the semi-open stage. The spikes retain their shape and color excellently, making them ideal for:

• picking bouquets and field bouquets

• organic bridal bouquets

• arrangements in hotels and events

• modern, natural and ecological floral designs

The combination of sturdy stems and airy flower heads makes Blue Boy BIO versatile and aesthetically attractive.

Excellent for dried flowers

Besides fresh use, Blue Boy Organic is also very suitable as a dried flower. When the flowers are harvested half-open and dried slowly, the intense blue color is retained and the flower heads remain intact. Dried Blue Boy Organic is ideal for:

• sustainable and organic dried bouquets

• natural wall decorations

• boho and field bouquets

• long-lasting interior decoration

The organic character of the flower makes it extra attractive to consumers who consider sustainability important.

Cultivation advice for organic cut stems

Key growing points:

• Sowing: February–April under glass or directly outside from April

• Plant out: after the last frost

• Planting distance: 20–25 cm for optimal stems and air circulation

• Soil: light, well-drained and nutritious, preferably with organic compost
