A prolifically flowering and colorful cut flower with full, often double blooms. Ideal for bouquets and borders, it brings long-lasting color and charm to the garden and vase.
Callistephus , commonly known as Chinese asters, are a valuable addition to any cut flower garden and offer a wide range of colors and shapes that enhance flower arrangements. Callistephus chinensis is the most important species for cut flowers and produces daisy-like flowers with a central disc surrounded by colorful ray florets. They are available as single, semi-double, or double flowers.
Callistephus can be used in a variety of flower arrangements, adding vibrant color and texture. They're often used in mixed bouquets and as focal points, thanks to their bright colors and variety of flower shapes. Their sturdy stems make them easy to handle.
Asters prefer cool temperatures and grow best in spring or fall, especially in areas with hot summers. Sow seeds indoors 6–8 weeks before the last frost date, or directly in the garden after the danger of frost has passed. Seeds should be lightly covered with soil.
Transplant the seedlings into the garden when they are about 7–10 cm tall, spacing them 20–30 cm apart to promote good air circulation and reduce the risk of disease. For a continuous supply of flowers, succession planting is recommended, sowing new seeds every few weeks.
Keep the soil consistently moist, but not soggy, and fertilize every few weeks with a balanced fertilizer. Rotate the planting location every year to prevent soil-borne diseases such as fusarium wilt and aster yellows. Harvest the flowers when they are fully open, but not yet overripe.
