Centaurea cyanus 'Blue Boy' is a beautiful cut flower with vibrant, intense blue flower heads that instantly attract attention. This variety is a modern, robust interpretation of the traditional cornflower, ideal for both professional cut flower growers and creative florists looking for a reliable, colorful eye-catcher.

'Blue Boy' combines graceful flowers with long stems, making it suitable for fresh bouquets, field bouquets and dried flower arrangements.

Striking blue flowers with a natural look

Centaurea cyanus 'Blue Boy' is characterized by its bright blue, open flower heads with delicate ray florets that create an airy rosette shape. The flowers have a natural, wild appearance and are perfect for:

• field and picking bouquets

• romantic and natural flower arrangements

• bridal work and ceremonies with soft or contrasting tones

• botanical styling for events, hotels and interiors

The intense blue colour adds a fresh and vibrant touch and creates an excellent contrast with pastel shades or white in bouquets.

Strong, long cutting handles for professional use

'Blue Boy' develops straight, sturdy stems of 60–90 cm, depending on location and care. These stems are robust and can withstand transport, making the flower ideal for large-scale production and commercial distribution.

Thanks to its branched growth habit, the plant produces multiple harvestable stems per season, guaranteeing a reliable harvest for both small florists and large growers.

Good vase life and versatility in floral arrangements

Centaurea cyanus 'Blue Boy' offers an average vase life of 7–10 days, especially when harvested in the semi-open stage. The flowers retain their shape and color exceptionally well, making them ideal for:

• picking bouquets and field bouquets

• bridal work with fresh blue accents

• packages for hotels and events

• modern, natural and botanical floral designs

The combination of long stems and airy flower heads makes Blue Boy exceptionally versatile and aesthetically appealing.

Excellent for dried flowers

Besides fresh uses, Blue Boy is an excellent choice for dried flowers. Harvesting the flowers just as they begin to open and drying them gently preserves the intense blue color and keeps the rosette shape intact. Dried Blue Boy is ideal for:

• field bouquets and cut flowers for interior decoration

• sustainable and long-lasting flower arrangements

• modern botanical wall installations

• combination with neutral or pastel colours for a fresh look

This means that Blue Boy remains a valuable flower even outside the fresh season.
