Seed Treatment:
• Soak seeds in warm water for 4–6 hours before sowing to encourage quicker germination
• Seeds are small — sow shallowly or surface sow
When to Sow:
• Indoors: Start 4–6 weeks before last frost
• Outdoors: Direct sow in early spring or in late summer to early fall in mild climates
Light Requirements:
• Prefers full sun
• Can tolerate light shade, especially in warmer climates
Soil Requirements:
• Prefers well-draining, moderately fertile soil
• Avoid overly rich or wet soils, which can cause leggy growth
• pH range: 6.0–7.5
Sowing Instructions:
• Sow seeds ⅛ inch (3 mm) deep or surface sow and press lightly into soil
• Use grow lights to maintain 12–16 hours of light per day.
• Humidity: Use a humidity dome or clear cover to maintain consistent moisture during germination. Open the dome BRIEFLY once per day to allow fresh air in and reduce mold risk. Remove the dome entirely once seedlings emerge.
• Keep soil evenly moist until germination
• Ideal temperature: 15–18°C (59–65°F)
• Germinates in 7–21 days
Watering:
• Water gently and consistently during germination
• Once established, water moderately — avoid overwatering
Spacing:
• Thin or transplant to 6–10 inches (15–25 cm) apart
Growing Tips:
• Blooms open in the evening with a sweet, clove-like fragrance
• Flowers are ideal for scented night gardens
• Use near patios, walkways, or windows where scent can be enjoyed
• Blooms in spring to early summer
• Excellent for containers, beds, and borders
• Best grown as an annual in most climates
