Harvest Tips
Cut flowers in early morning when fully open for fresh arrangements. Harvest entire stems just above the first set of leaves. For drying, cut when flowers are fully colored but before they begin to fade, and hang upside-down in a cool, dry place. Leave some seed heads on the plant for wildlife and self-seeding
