Aster (Aster Tongolensis Wartburg Star) - Aster Wartbur Star flower seed often produces flowers the first year after sowing. The 2 1/4-inch blooms come in varying shades of light violet-blue, with tufted gold centers. They bloom mid-summer to late fall. This is an extraordinary Aster, easy to grow, long lived, very showy, and makes great cut flowers! Good for rock gardens, landscaping, edging and suitable for containers. The dark green foliage forms dense, tufted mats in full to part sun, and moist but well-drained soil. Sow Aster Wartburg flower seed indoors in early spring using starter mix. Press flower seed into soil and barely cover. Keep the flower seed damp and transplant plants into the garden 20 inches apart.
