How to Grow
1800 seeds/gram. One of the best long-flowering perennial wildflowers. Start seed indoors in a soil-less mix in early spring for bloom the same season. Keep at 24 C (75 F) for the 15 to 20 day germination period. After that, grow on under lights at a slightly cooler temperature before hardening off and transplanting outside to a sunny spot. Outdoors, direct sow seed from mid May to early June – keep the soil moist during the germination period. Thin seedlings to stand 30 cm (12″) apart in formal plantings. Divide plants every two to three years. Blooms June through fall. Seed can also be directly sown outdoors in the fall and early spring.
