    Direct sow in late fall by lightly pressing the seeds into the soil's surface. For spring planting, mix seeds with moist sand and store in the refrigerator for 60 days (cold stratification) before sowing.

  • A Note on Cold Stratification

    These seeds require cold, moist stratification. To naturally stratify the seeds, plant outdoors late fall on a weed-free site and allow seeds to overwinter. 

     

    To artificially stratify the seeds, place the seeds and a moist medium (such as a damp paper towel, coffee filter, sand, or vermiculite) in a labeled, sealed plastic bag and store in a refrigerator (33-40°F) for the amount of time noted on the growth chart before sowing.
