Sulphur Paintbrush Castilleja sulphurea 100 mg (approx 900 seeds) Seeds For Planting

To break its dormancy, this seed needs to be stratified; mix the seed with moist sand and store it in the refrigerator for 60-90 days before planting. In the spring, plant the seed on the surface of loose soil at the base of a larger plant. For fall planting, sow untreated seed on the surface of loose soil near other plants, or sow a low-growing native grass along with the seed.
