Planting & Care

For best results, scarify seeds by nicking the seed coat and soak in water for 24 hours before sowing. Cold stratification can improve germination; sow seeds indoors 6–8 weeks before last frost or directly outdoors in fall. Press seeds into moist, well-drained seed-starting mix and cover lightly. Keep at 65–70°F (18–21°C) and maintain consistent moisture until germination.

Once seedlings have several true leaves, transplant to individual pots and harden off before planting outdoors after the danger of frost has passed. Choose a sunny location with well-drained soil. Water regularly during establishment, and mulch to conserve moisture. Deadhead spent blooms to encourage continued flowering and prevent unwanted self-seeding.
