Abundant cluster blooms and sunny yellow color

Each stem of the Serenade Yellow bears a cluster of multiple flowers, creating a dense and lush bloom. The semi-double flowers are a warm yellow with a contrasting yellow center, creating a harmonious and striking effect in borders, pots, and bouquets.

Thanks to its compact clusters, the Serenade Yellow is excellent for cut flowers, as multiple blooms per stem create a full, professional look. In borders or pots, this aster adds a cheerful and sunny accent that combines perfectly with other summer and autumn flowers.

Production cycle and cultivation time

The production cycle of Serenade Yellow is approximately 14 weeks from sowing in spring. By using day-length manipulation techniques, flowering can be accelerated or timed to specific harvest times.

This predictable flowering and compact growth period make the Serenade Yellow particularly suitable for professional cut flower cultivation, where planning and harvesting are easy to coordinate.

Fusarium tolerance and cultivation advice

Asters are susceptible to Fusarium wilt, a fungus that can cause root and stem wilt. For healthy and productive plants, it is recommended to:

• Change location annually or disinfect the soil.

• Avoid overwatering and ensure well-draining soil.

• Promote cultivation in a sunny and airy environment.

With these precautions, the Serenade Yellow can flower profusely and maintain its full cluster shape.
