Stratification - Instructions indicate 30 days of cold moist storage. After drying, our seed was then added to a small bag of vermiculite and placed in refrigerator. It will be planted indoors February 2021. It has been our experience that in most cases, additional time in the cold storage does not effect germination. All of our seeds are put in cold storage at approximately that same date for no other reason other than convenience.
