Harvest Tips
For lei-making, harvest flowers in early morning when they are fresh and fragrant, just after the dew dries. Cut stems with flowers and leaves intact using clean, sharp shears. Use immediately or refrigerate in water for short-term storage (1-2 days). For medicinal or cultural use, harvest flowers and small branches with respect to the plant's slow growth; never over-harvest as this is a rare native species.
