Parts Used
Roots - Picked end of first year in the Fall. Leaves - Picked during first or second year. Flowers - Picked in second-year mid-season when mullein sends up it's flowering stalk.

Growing
Since mullein is a biennal, it should be grown by seed. It grows throughout North America. I would sow the seeds on bare ground and rake lightly. It typically grows in disturbed ground, so is not picky on the soil.
