The above propagation data sourced from Claude AI

Pre-treatment: A 6-week cold moist stratification at 34 to 37°F. Sow seeds directly onto a peat-lite mix and cold chill, or stratify seeds in a 50:50 sand:peat moss mix in a ventilated ziplock bag. Moisten seed and media and allow to imbibe water overnight before placing in cooler.
