Harvest Tips
For medicinal use, harvest roots in autumn after foliage dies back or in early spring before growth begins. Dig carefully to extract roots without damaging the crown. Dry thoroughly (2-3 weeks in warm, dry location) before storing. For cut flowers, harvest in early morning when blooms are fresh; they have a short vase life of 3-5 days.
