"To muse, to creep, to halt at will, to gaze ... such sweet wayfaring" William Wordsworth
How do they harvest it? Where does the oil come from, the stalk or the flower?
Diane, the oil comes from the seeds. So I guess is it not harvested until seeds set. I believe harvesting is done with header much the same as wheat.
Glad you posted this close-up, it's a lovely bloom.
