Lavender is the soul of Provence” Lavender Fields are a sight not to be missed, the color, the texture, and the scent of a lavender field encapsulate for many the essence of Provence. Lavender is said to heal insect bites and burns as well as repel insects. It can soothe headaches if you apply it to the temples and it helps you sleep if you have the flowers by your pillow. Late June through July is the best season for lavender in Provence.
