- For earliest colour, sow seeds in warmth 6 to 8 weeks before last frost covering seeds with 1/16 inch fine soil.
- Germination takes 10-20 days with the seeds needing darkness to germinate.
- Keep soil moderately moist during germination
- For later blooms sow directly outdoors in mid spring after danger of serious frost has passed.
- Seeds can also be sown outdoors in late summer, or earliest autumn in mild winter areas.
- Gradually acclimatize young plants outdoors after all frosts have passed, planting out 6-8 inches between plants.
