Aster – Peony Duchess Mix

Growing Temp 65°F – 75°F
Days to Maturity 90-120 days

Ease of Cultivation and uses: Peony Duchess Aster Mix is a classic annual aster blend prized for its large, fully double, peony-like blooms in a rich mix of colors. Plants form upright, well-branched clumps that bloom heavily in late summer to early fall, making them invaluable for extending color in the garden when many other flowers are fading. These asters are easy to grow, dependable, and well-suited for beds, borders, and cutting gardens. Their strong stems and long vase life also make them excellent cut flowers.

Direct Sowing: Sow seeds outdoors after all danger of frost has passed and soil temperatures are at least 60–65°F. Plant seeds about 1/8 inch deep in well-drained soil and keep the surface evenly moist until germination, which typically occurs in 7–14 days. Once seedlings are established, thin to 12–18 inches apart to allow for good air circulation and strong plant development. Plants will bloom approximately 90–110 days from sowing.

Early Sowing for Seedlings: For earlier blooms, start seeds indoors 6–8 weeks before the last expected frost. Sow seeds 1/8 inch deep in a quality seed-starting mix and maintain temperatures of 65–70°F for germination. Once seedlings have developed true leaves, harden them off gradually before transplanting outdoors after the last frost. Space plants 12–18 inches apart in full sun and well-drained soil. Water well after transplanting to help plants establish quickly.

Harvesting: Peony Duchess Aster blooms are ready to cut when flowers are fully open and vibrant. Harvest in the morning for best vase life, cutting long stems at an angle and placing them immediately into water. Regular cutting encourages the plant to keep producing new blooms through the late summer and early fall season.
