*This variety requires a stratification period of 7 days in the cold.
Cold stratification:
This method makes it possible to break the dormancy of seeds which only germinate after a period of exposure to cold and humidity. Cold stratification, which is similar to what nature would do in winter, alters the seed coat that surrounds the seeds and protects them from air and water. There is no need to freeze the seeds however, a cool temperature between 0°C and 10°C is satisfactory.
