A cheerful annual with sunny white-and-yellow “fried egg” blooms! Fast-growing and loved by pollinators. Ideal for cottage gardens, borders, containers, and wildflower meadows.
For optimal germination rates, initiate seed propagation indoors under controlled conditions—unless the species exhibits a high sensitivity to root disturbance. This approach allows precise regulation of temperature, humidity, and light, improving germination consistency and seedling viability. Do not skip any recommended seed treatments, as they are essential for uniform and successful germination.
⚠️ Keep soil evenly moist during germination. DO NOT LET IT DRY OUT—once seeds begin absorbing water (imbibition), drying can kill the seed embryo, and even brief dryness after sprouting can kill seedlings.
Seed Preparation
Soak seeds in clean water for 6–12 hours.
Cold Stratify: Mix seeds with moist sand or a damp paper towel, place in a sealed plastic bag, and refrigerate at 2–5°C (36–41°F) for 10–14 days.
Check Regularly: If seeds sprout in the bag, remove gently and plant immediately.
Optional GA₃ treatment: Gibberellic acid may help, but can destroy seeds if misused. Only use if experienced.
Best Time to Sow
Outdoors: Early spring after last frost, or fall in mild winter climates.
Indoors: 4–6 weeks before last frost date.
Germination Requirements
Temperature: 13–18°C (55–65°F)
Light: Use grow lights to maintain 12–16 hours of light per day.
Germination time: Up to 30 days AFTER stratification
How to Sow
Depth: Surface sow — press gently into soil, do not cover.
Moisture: Keep evenly moist but not waterlogged.
MODERATELY SENSITIVE TO ROOT DISTURBANCE: Start in biodegradable pots, peat pellets, or deep cell trays so you can plant the whole container without disturbing roots. If you must transplant seedlings from a tray, do it very early—when they have only 1–2 true leaves—and disturb the roots as little as possible.
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.
