In July the lavender is harvested in Provence. Before the lavender is picked, head up to the bright purple fields just north of Aix-en-Provence in Valensole. The name of the town and the plateau where the lavender grows comes from the Latin word vallis meaning valley and solis which means sun. The lavender in Valensole is usually harvested around July 14th depending on the year.
Other towns in Provence also celebrate the season with Lavender Festivals so if you are visiting the Luberon you can head to the town of Ferrassières where the festivities kick off on July 5th. Activities include guided walks through lavender fields and a visit to a distillery where the essential oil is extracted for the fragrance industry. www.fete-lavande.com/crbst_1.html
