Harvest Tips
For cut flowers, harvest in the morning when stems are fully hydrated, selecting flowers that are fully open or just opening. Cut with a sharp knife, removing lower foliage. Flowers last 1-2 weeks in a vase with fresh water changed every 2-3 days. For seed collection, allow flowers to dry on the plant and collect brown seed heads in fall; store seeds in cool, dry conditions.
