Vibrant clusters with classic charm: Sweet William – Tall Double Mix offers dense, eye-catching flower heads in a range of pink, red, white, and bicolor shades. These biennials (often grown as annuals) are known for their clove-like fragrance and tall, sturdy stems, making them excellent for cutting gardens and borders. They are moderately easy to grow and ideal for gardeners who enjoy attracting pollinators and creating lush displays.

Direct Sowing: Sow seeds directly outdoors in late spring to early summer for blooms the following year, or in early spring in mild climates for same-year flowering. Choose a location with well-drained soil and full sun to partial shade. Sow seeds thinly, cover lightly with soil, and keep moist during the 10–14 day germination period. Thin seedlings to 6–8 inches apart once established for proper airflow and strong growth.

Early Sowing for Seedlings: Start seeds indoors 6–8 weeks before the last frost in seed trays or small pots using a light potting mix. Maintain a temperature of 60°F–65°F. When seedlings have a few true leaves and outdoor conditions are stable, harden them off gradually and transplant them 6–8 inches apart in the garden. Provide consistent watering until they are established, and mulch to retain soil moisture.

Harvesting: Harvest Sweet William when flower clusters are about half open for the longest vase life. Use clean, sharp scissors and cut in the early morning when flowers are well hydrated. Regular deadheading encourages more blooms and keeps the plant tidy. For dried flowers, hang stems upside down in a dry, well-ventilated area out of direct sunlight.
