Harvesting: Fresh foliage can be harvested any time until plant flowers. Cut leaves as close to stem as possible. Seeds should be harvested 2 to 3 weeks after flowering begins, after the flower heads have turned brown. Cut flower heads with stem and place in paper bag before seed becomes too mature and falls to the ground. Heads should be placed in bottom of bag and the top of the bag should be tied shut around the stems. Seeds will fall to the bottom of the bag. Store seeds in airtight glass jar.
