Germination - Seed requires 60 days of cold moist storage
Winter of 2019 - Seed was stored in a plastic bag, mixed with vermiculite, for two months. Vermiculite maintains moisture and help prevent molding. Seed was started indoors under florescent lights. A controlled environment, serves as a means of learning to identify seedlings, as well become familiar with their idiosyncrasies. Sadly, germination rate was sporadic.
Winter 2020 - Seed from same source was planted outside in the fall. Covered with soil and protected from the elements with old glass window. Significantly, higher germination rate!
