Native to France and the western Mediterranean, it is now cultivated worldwide for its volatile oil. It is grown as a garden plant as far north as Norway. Lavender is a perennial shrub, growing to about three feet, producing spikes of violet-blue flowers that extend above the foliage. Some varieties have flowers of pale pink, dark purple, white, or magenta and are harvested toward the end of flowering season when the petals have begun to fade. They are generally picked by the end of July to obtain maximum strength in its essential oils, with sixty pounds of flowers yielding about sixteen fluid ounces of oil.
