The above propagation data sourced from Claude AI

Pre-treatment: Scarification by rubbing seeds between two pieces of sandpaper approximately 15 times. Cold moist stratification for 28 days. Alternatively, warm stratification can be accomplished by subjecting seeds to 45°C/15°C conditions for 8 and 16 hours respectively for 15 days.

Establishment: Germination rates of untreated seed are extremely low - under 3%. Warm stratification should not exceed 15 days as this results in significant decreases in viability. Germination rates of scarified seeds are strongly correlated with the temperature at which planted seeds are kept. In some cases, stratification alone improved germination over the control, but in other cases it resulted in lower germination due to fungal growth.
