Germination Information
Pre-treatment: Seeds are scarified using boiling water or H2S04 acid bath, then soaked in water. This is followed by a warm-moist stratification for 45 days and a cold-moist stratification for 90-140 days.
Establishment: Seeds are collected by hand from locally native plants. The drupes are hand collected in late August and early September when they turn orange-red. Seeds are tan at maturity. Fruits are collected in plastic bags are are kept refrigerated prior to cleaning. There was no appreciable difference in germination percentages between acid scarified seed/ 90 day cold, moist stratification vs. non-scarified seed/5 month cold, moist stratification.
