Callistephus chinensis (Aster) Serenade Blue tipped White – Trosaster with elegant two-tone flowers

The Callistephus chinensis (Aster) Serenade Blue Tipped White is a stunning variety from the Serenade series, beloved for its clustered blooms and unique bicolor flowers. Each stem bears an abundance of semi-double flowers with a yellow center, the blue petals subtly tipped with white. This combination of colors creates an elegant and fresh look, ideal for gardens, borders, and bouquets.

With a flower diameter of approximately 3 cm and compact, abundant clusters, the Serenade Blue tipped White is perfect for cut flower cultivation, pots and borders, and offers long-lasting and attractive flowering.

Abundant cluster blooms and subtle colours

The clusters of flowers make this aster particularly decorative. Each stem bears several semi-double flowers that together form a dense and abundant bloom. The yellow center contrasts beautifully with the blue petals with white tips, giving the flowers added dimension and elegance.

Thanks to these compact clusters, the Serenade Blue Tipped White is ideal for cut flowers, as multiple blooms per stem create a full, professional look. In borders and pots, it adds a fresh and stylish touch, combining well with other summer and autumn flowers.

Production cycle and cultivation time

The production cycle of Serenade Blue Tipped White is approximately 14 weeks from sowing in spring. By using day length manipulation techniques, the start of flowering can be accelerated or synchronized with specific harvest times, which offers a significant advantage for professional cut flower growers.

This predictable flowering and short production time make it a reliable choice for both commercial and residential applications.

Fusarium tolerance and cultivation advice

Like all asters, the Serenade series is susceptible to Fusarium wilt, a soil-borne fungus that can cause root and stem wilt. To maintain healthy and productive plants, it is recommended:

• Change location annually or disinfect the soil.

• Avoid overwatering and ensure well-draining soil.

• Grow in a sunny and airy environment to reduce mold formation.

With these measures, the Serenade Blue tipped White can flower profusely and maintain its full cluster shape.
