Seed Treatment:
• Seeds are very fine and light-sensitive — do not cover with soil
• Optional: Soak seeds in warm water for a few hours to encourage quicker germination (not essential)
When to Sow:
• Indoors: Start seeds 6–8 weeks before the last frost
• Outdoors: Transplant after all danger of frost has passed (not recommended to direct sow due to tiny seeds)
Light Requirements:
• Prefers full sun to partial shade
• Performs best in afternoon shade in hot climates
Soil Requirements:
• Grows in moist, well-draining soil
• Prefers rich, fertile soil with added compost
• pH range: 6.0–7.5
Sowing Instructions:
• Surface sow — do not cover seeds
• Press gently onto moist soil
• Mist lightly to avoid displacing seeds
• Ideal germination temperature: 65–75°F (18–24°C)
• Germination occurs in 10–21 days
Watering:
• Keep soil evenly moist during germination
• Water regularly once established, but avoid waterlogging
Spacing:
• Thin or transplant seedlings to 18–24 inches (45–60 cm) apart
Growing Tips:
• Produces tall spikes of fragrant, tubular white flowers that bloom from mid to late summer
• Attracts moths, bees, and hummingbirds
• Best grown as an annual, though may self-seed in mild climates
• Ideal for evening gardens, borders, and cottage-style landscapes
• Remove spent flower stalks to encourage continued blooming
