Fleurs du Roi, Versailles.
For anyone in the Versailles area, this exhibition of botanical art is worth a visit. The show includes watercolours on vellum, paintings and also features a newly replanted scented garden. It’s on until the end of September and is in the Grand Trianon, right next to Marie Antoinette’s famous estate. http://en.chateauversailles.fr/news-/events/expositions/fleurs-du-roi-en
