Lavender season is in full swing in Provence, and tourists are flocking to destinations like Sénanque Abbey to see the sweet-smelling spectacle of fields painted purple. The monks here at Sénanque cultivate lavender for their livelihood and these days the herb is in demand mostly for its essential oil, which lends a soothing scent to cosmetics, cleaning products, and even food. Lavender ice cream, lemonade, and cakes are popping up on menus around the globe.
