Check the code at the end of the description for specific germination requirements.
(1) Germinates at temperatures between 60-75°F.
(2) Larger seeds need to be covered with soil at least as thick as the seed itself. May be slow and erratic to germinate.
(3) These seeds need a period of cold stratification for successful germination. Best results are obtained when the seeds are kept warm and moist for 2 weeks followed by temperatures of 33-35°F for 4-6 weeks or until germination starts.
(4) No special requirements, but germination may be slow and erratic.
