The above propagation data sourced from Claude AI
Pre-treatment: Stratification for 2 to 4 weeks. Cold stratification involves sowing in plug trays, ensuring media is moist, covering with an inverted flat, stacking, and placing in a walk-in cooler at 40°F. Check periodically for germination or need for moisture.
Establishment: Collected in Grand Canyon National Park, Arizona. Fertilizer used is Peters Peat Lite Special 20-10-20 at a rate of 200-mg/l nitrogen.
