Harvest Tips
Cut flowers in early morning when fragrance is strongest, immediately after flowers fully open. Use sharp pruners or scissors to cut stems just above a leaf node. Flowers are best harvested when fully open but still fresh. For perfume production, flowers are typically harvested at peak bloom and processed fresh or dried. Plant can be cut back after main flowering season to encourage bushier growth and more flowers.
