Valkyrie China Aster brings a striking presence to summer borders and cut flower arrangements with its full, rounded blooms that emerge 110-120 days after sowing. This open-pollinated cultivar of Callistephus chinensis grows as a compact bush, reaching maturity within a single season when started early indoors. The variety's name evokes the warrior spirit of Norse mythology, and it lives up to that reputation as a dependable performer that rewards early establishment with sturdy stems worthy of the vase.

Valkyrie China Aster produces blooms that are genuinely prized by florists and home arrangers for their architectural quality in fresh arrangements. The flowers open gradually from the outside ray florets inward, giving arrangers a window to harvest at precisely the right moment for maximum vase life. Early planting is essential; sow transplants 6-8 weeks before your last frost to avoid the short stems that plague late plantings, and you'll be rewarded with the tall, straight stems this variety naturally produces.
Valkyrie China Aster excels in two distinct roles: as a border plant that provides reliable midsummer color in the garden, and as a premium cut flower for fresh arrangements. The blooms transition from bud through opening over several days, making them particularly valuable for florists and home arrangers who time their cutting carefully. Fresh flowers can be conditioned immediately by placing them in water as the outer ray petals begin to open, or allowed to mature fully before drying for dried arrangements.

Sow seeds 1/8 inch deep in 72-cell flats or preferred seedling containers 6-8 weeks before your anticipated transplant date. Keep seedlings warm; heat promotes stronger development. Plan to move transplants outdoors well before summer heat arrives, as early establishment is crucial for achieving full plant height and stem length.
Harden off seedlings gradually before moving to the garden. Transplant outdoors once soil temperatures consistently reach 65-70°F (18-21°C). Space plants 6 inches apart. Early planting is essential to prevent short stems; establish plantings as soon as frost danger passes.
Direct seed once soil temperature reaches 65-70°F (18-21°C). Sow seeds 1/8 inch deep. Provide support structures early as seedlings develop. Space seedlings to 6 inches apart.
Cut flowers when the outside ray florets are just beginning to open and place immediately in clean water to condition. For dried arrangements, wait until blooms are fully open before harvesting. Timing the cut at the early-open stage extends vase life significantly.
Pinching is not required. The plant naturally develops its full, bushy growth habit without intervention.
