Pure white peony-form flowers distinguish Tower White from single-flowered asters, offering the lush, romantic blooms that make these plants heirloom treasures. The 110 to 120-day maturity window means you can time plantings to reach peak bloom just as late summer heat breaks, extending your cutting season into fall when white flowers feel especially precious. Starting from seed indoors 6 to 8 weeks before planting gives you control over timing and abundant flowers without expensive transplants.
Tower White China Aster thrives as a border plant, where its compact bush habit and generous flower production create layers of soft, white texture. Cut flower gardeners prize this variety for its long stems and peony-form blooms, which hold their shape and freshness longer than many other aster types.
No timeline data available yet for this variety.
Sow seeds 1/8 inch deep into 72-cell flats or your preferred seedling container 6 to 8 weeks before your planned outdoor planting date. Maintain soil temperatures between 65 and 70 degrees Fahrenheit for reliable germination. Heat and reduced daylength will naturally trigger flowering once established.
Transplant seedlings outdoors after the last frost date, hardening them off gradually to full sun. Establish plantings early in the season to allow ample time for full stem development before bloom.
Direct seed once soil temperature reaches 65 to 70 degrees Fahrenheit. Provide support structures where seeds are sown directly into beds.
For fresh arrangements, cut stems just as the outer ray florets begin to open and immediately place them in water to condition. For dried flowers, allow blooms to fully open on the plant before harvesting for drying.
Pinching is not required for Tower White China Aster. The plant's naturally compact bush habit branches well without manual intervention.
