Propagation & Germination
- Stratification:
- Warm then cold/moist stratification (double dormancy) — 90–180 days

The above propagation data sourced from Claude AI
Pre-treatment: Seeds treated with dry heat at 120 C for 5 minutes resulted in decreased germination.
Establishment: The plant is found within the mattoral vegetation association of California. Avoid pre-treatment with dry heat as it decreases germination.
