Such a beautiful picture! The scarf is Jardin à Sintra, designed by Annie Faivre, belongs to the autumn/winter 2017 collection.
This is one of my favourite scarves in this colourway (Gris/Bleu glacier/Vert). I wear it almost every day in the autumn.
The design history published by Hermès:
"In Portugal, on the Atlantic coast, just twenty kilometers from Lisbon, lies Sintra, classified as a UNESCO World Heritage “Cultural landscape” in 1995. Near the town's historic center, the palace and park of Monserrate add their astonishing beauty. Inspired by Gothic, Indian and Moorish art and nestled in luxuriant grounds, this fantasy of stone and trees was acquired by a British textile magnate in the second half of the nineteenth century. Species brought here from the four corners of the globe thrive in the gentle climate. Organized by origin, they create a haven of unrivaled tranquility. Designer Annie Faivre was dazzled by the site’s beauty: her carré is designed to evoke the luxuriant, romantic park populated with palms, cacti, banana trees, eucalyptus, wisteria, holly, tree ferns, cork oaks and agaves."
