Seeds need exposure to 30-60 days of cold (aka “cold stratification”) before they will germinate. Sow seeds outside in late summer, fall or early spring (before March 1st) so they are naturally exposed to the cold. Prepare area by loosening soil surface with a rake. Hand broadcast (sow) seeds evenly over area. Water seeds with a light sprinkle after sowing. Or sow seeds onto the snow! To start seeds inside, in January or February, mix the seeds into ½ cup of moist sand (or paper towel) and place in a sealed plastic bag and place in the refrigerator for 60 days before planting. Then start seeds in containers 3/1-6/15 at 70°. Days to germination: 7-14. Transplant outside May-July 2-3' apart. Plant in part shade to full sun location. Plants will grow better in a wetter area or with watering.
Harvest stems for fresh and dried arrangements. Harvest when seed heads have matured but still show some green color. Fully tan seedheads can be harvest too.
Collect seeds heads in fall and dry them.
