Harvest

Timing:

    • Flowers: Best harvested in the summer during peak bloom when the plant’s medicinal properties are most potent.
    • Roots: Typically harvested in autumn after the plant has gone dormant. The roots can also contain some medicinal properties, though they are less commonly used.

Method:

    • Use scissors or pruners to carefully cut the flower heads without damaging the plant. Harvest on a dry day to prevent moisture from causing mold during drying.
    • For roots, carefully dig around the base of the plant, loosening the soil to remove the root system intact.

Storage:

    • Flowers should be dried in a cool, shaded, and well-ventilated area. Once dried, store them in airtight containers away from sunlight.
    • Dried flowers are most potent within one year, while roots, if used, can last up to two years.
