Harvest Tips
Cut flower stems early in the morning when stems are turgid. Cut just above a leaf node for continued branching and secondary blooms. For drying, harvest when flowers are fully open but before they begin to fade; hang bundles upside down in a warm, dark, well-ventilated space for 2-3 weeks. Fresh arrangements last 1-2 weeks in water.
