Harvest Tips
For cut flowers, harvest plumes when fully developed but before they start to fade, cutting stems early in the morning. Plumes can be air-dried by hanging in bundles upside-down in a warm, dry location for long-lasting arrangements. For seed collection, allow flowers to completely dry on the plant, then harvest capsules and extract seeds.
