Remove flowers from dried lavender stems and save for another use. Soak the stems in a water/potassium nitrate bath, 1 cup water to 1 tablespoon potassium nitrate, for thirty minutes. Remove from solution and dry completely on paper towels. Place the end of a stick in an incense holder or a jar of dry sand and light. They will burn slowly like incense. Do not leave unattended.

Take all necessary precautions with any burning object, whether they are candles, herbs, or incense, and be sure to place them on flame-proof dishes, perhaps in a bit of sand.
