Callistephus chinensis.
Elegant, needle-like blooms that open into richly saturated dark blue flowers, often appearing deep blue-violet to indigo-purple in cooler climates. Plants reach 24″ tall with 3–5″ blooms and offer excellent vase life, making them ideal for cut flower gardens and borders.
Approx. 25-30 seeds per packet (0.05g)
Sow indoors 6-8 weeks before last frost for earlier blooms. Otherwise, direct sow outdoors after last frost date. Barely cover the seeds. Space or transplant 12-18" apart. Seeds germinate in 10-14 days.
