Propagation & Germination
- Stratification:
- Cold/moist stratification required — 30–60 days
- Germination Time:
- 7–21 days
- Notes:
- Seeds germinate readily after cold stratification; sow in fall or stratify for 30-60 days.
Pre-treatment: Seeds can be placed in 0-1°C (32-34°F) for a 10-day cold stratification treatment and then exposed to 22-25°C (72-77°F). Alternatively, seeds can be treated with Carboxin or a similar compound to prevent head smut (Ustilago bullata) in subsequent seed crops.
Establishment: Germination time may vary depending on the conditions. Seedlings grow quickly and may flower in the first season but do not produce sufficient seed in the first season to make harvesting worthwhile.
