Aster Tower Blue Seeds, 25 Seeds

Aster Tower Blue flowers are a striking variety of China Asters (Callistephus chinensis) known for their tall growth and vibrant blue blooms. Their densely packed, feathery petals create a full, pom-pom-like appearance that adds texture and depth to gardens and floral arrangements. These flowers thrive in well-drained soil with plenty of sunlight, blooming from late summer to early fall. Their strong stems make them an excellent choice for cut flower arrangements, as they have a long vase life and hold their shape well. Aster Tower Blue flowers bring a bold yet elegant touch to any garden, attracting pollinators like bees and butterflies while providing a stunning display of color.

Transplant (recommended) - Sow 1/8" deep into 72-cell flats or preferred seedling container, 6-8 weeks before last frost. Heat and reduced daylength initiate flowering. Establish plantings early to avoid short stems.

Direct seed - After your last frost date and when soil temperature is 65-70°F (18-21°C). Provide support. Row cover or insect netting helps prevent the spread of Aster Yellows Virus by leafhoppers. Pinching not required.
