How to Grow Chinese Forget-Me-Not Seeds (Cynoglossum amabile):
Chinese Forget-Me-Not is an easy cool-season annual with clusters of sky-blue flowers. Sow seeds directly outdoors in early spring after the last frost, or in fall for earlier spring blooms in mild climates. You can also start indoors 4–6 weeks before last frost. Seeds are small: sow very shallow, about 5–8 mm (¼ in) deep or just barely covered, and gently firm the soil. Keep the surface evenly moist until germination; sprouts usually appear in about 5–10 days when soil is around 18–24°C (65–75°F). If starting indoors, keep trays slightly darker or covered until they sprout, then move to bright light. Transplant or thin seedlings to 20–30 cm (8–12 in) apart. Plant in full sun for best flowering, but in hot areas give morning sun with afternoon shade. Use well-drained, average to moderately rich soil; avoid heavy clay or constantly wet spots.
How to Care for Chinese Forget-Me-Not:
Water regularly to keep soil lightly moist, especially while plants are young, but avoid soggy conditions to prevent mildew and rot. Once established, they handle short dry spells but bloom best with steady moisture. Fertilizer is minimal—too much nitrogen causes leafy growth and fewer flowers—so a light compost mix-in at planting or a gentle balanced feed once mid-season is enough. These plants branch well without pinching. Deadhead faded blooms if you want a longer flowering window and fewer volunteer seedlings; if you like natural reseeding, leave some flowers to form seed. They’re generally low-pest, but watch for slugs/snails on seedlings and occasional aphids; simple hand removal or a water spray usually works. In long, hot summers flowering slows, so extra shade and moisture help them last longer.
