How to Start
-
Cold-stratify the seeds for approximately 4 weeks at about 40°F (4°C).
- After stratification, surface sow onto moist, well-drained seed-starting mix. Because the seeds are small, avoid burying them deeply.
- Keep the medium evenly moist but not saturated, with good air circulation.
-
Maintain a temperature around 70°F (21°C).
-
Germination may occur in approximately 3–4 weeks under suitable conditions.
- Once seedlings are large enough to handle, transplant them carefully into individual containers.
Set expectations: Germination can vary depending on seed preparation, temperature, moisture, light, and growing conditions. Plants grown from seed can also vary naturally in size, form, vigor, and flowering characteristics.
