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.
