Seed Treatment:
• Scarify seeds lightly (rub gently with sandpaper or nick with a blade)
• Soak in warm water for 4–6 hours prior to sowing for faster germination
When to Sow:
Indoors:
• Start 4–6 weeks before the last frost in your area
Outdoors:
• Direct sow in late spring after the danger of frost has passed
Light Requirements:
• Prefers full sun
• Can tolerate light shade, but flowering may be reduced
Soil Requirements:
• Grows in average, well-draining soil
• Adapts to poor soils, but thrives in moderately fertile soil
• pH range: 6.0–7.5
Sowing Instructions:
• Sow seeds ¼ inch (6 mm) deep
• Water gently and keep soil evenly moist until germination
• Ideal soil temperature: 65–75°F (18–24°C)
• Germination occurs in 7–14 days
Watering:
• Water regularly during establishment
• Once mature, plant is drought-tolerant but benefits from moderate watering
Spacing:
• Space plants 18–24 inches (45–60 cm) apart
Growing Tips:
• Nicandra physalodes produces purple, bell-shaped flowers followed by papery, lantern-like seed pods
• Named the "Shoo-Fly Plant" for its historical use in repelling insects
• Fast-growing annual that can reach 2–4 feet tall
• Great for cottage gardens, wildlife borders, or ornamental beds
• Can self-seed—deadhead if you want to prevent naturalizing
• Tolerates heat and dry conditions once established
• Caution: While not highly toxic, it is not edible and should be kept out of reach of pets and children
