The germination of Prairie Blazingstar seeds is greatly increased by placing them in a damp paper towel in a plastic bag and then refrigerating them for 30 days. You can sow cold-treated seeds in the spring or summer. If you prefer to avoid the cold treatment, plant your seeds in the fall. Your seeds should be planted about 1/8th of an inch deep and they will germinate in 20-25 days. We recommend that you plant them in full sun about 12-15 inches apart.
