Harvest Tips
Harvest leaves and flowers for herbal preparations when the plant is in full bloom (mid-summer). Cut stems with flowers just as heads fully open for best potency. Aerial parts are typically harvested in June-August and dried for tea, tinctures, or herbal remedies. For seeds, allow flower heads to fully dry on the plant, then collect and store in cool, dry conditions.
