Tower Yellow China Aster is a striking cut flower variety that delivers abundant, fully double peony-type blooms in a cheerful yellow hue. This open-pollinated cultivar of Callistephus chinensis reaches maturity in 110 to 120 days and grows as a compact bush, making it equally at home in garden borders or bunched fresh from the vase. The variety thrives when started indoors and benefits from early planting to ensure strong stem development, rewarding gardeners with long-lasting flowers that open progressively and hold their form beautifully in the vase.

The peony-type blooms set Tower Yellow apart, with their intricate, fully double petals creating an almost floral opulence that reads as genuinely luxurious in any arrangement. Starting these indoors 6 to 8 weeks before your last frost gives you control over stem length, a detail that matters enormously for cut flower quality. Early establishment prevents the common problem of short, weak stems, and the blooms continue to open gradually once cut, extending your vase life significantly.
Tower Yellow China Aster shines as a cut flower for fresh arrangements and a garden border accent where its bright yellow tones draw the eye. The variety performs exceptionally well for florists and home gardeners alike who want long-stemmed blooms suitable for bouquets and mixed arrangements.

Sow seeds 1/8 inch deep into 72-cell flats or your preferred seedling container 6 to 8 weeks before your last frost date. Keep soil warm and moist; heat promotes germination and helps initiate the flowering response.
Transplant seedlings outdoors after your last frost once they have developed true leaves. Space plants 6 inches apart. Establish plantings as early as possible in the season to allow sufficient time for strong stem development before blooming begins.
Direct seed once soil temperature reaches 65 to 70°F (18 to 21°C). This approach requires row cover or insect netting to protect against leafhoppers that can spread Aster Yellows Virus.
For fresh flowers, harvest when the outer ray petals have just begun to open. Cut stems and place immediately in water to maximize vase life. For dried arrangements, cut when blooms are fully open and allow to dry in a warm, airy location.
Pinching is not required for Tower Yellow China Aster, though selective pinching can encourage bushier growth and more branching if desired.
