In the Garden Where It All Began – Visiting Yves Rocher’s Roots in La Gacilly text Sandra Myhrberg Sitting on a hillside between La Gacilly and Cournon, the La Grée des Landes Eco-Hôtel & Spa opened its doors in 2013 as Brittany’s first fully ecological hotel. I had the chance to experience its offerings while tracing Yves Rocher’s roots in La Gacilly, an area directly tied to the brand’s founder, where a young Yves Rocher once wandered, picking the wild plants and flowers that would later shape his life’s work. The hotel’s twenty-nine rooms are floored and panelled in oak from sustainably managed forests. The restaurant, Les Jardins Sauvages, grows its own organic, locavore produce. And I must mention the spa that runs entirely on Yves Rocher’s plant-based rituals. I also visited Yves Rocher’s birthplace, where, in the 1950s, a teenage Yves Rocher, following a healer’s recipe for a hemostatic ointment made from lesser Celandine, hand-mixed his very first batches of cream after losing his father. That ointment, made and sold from his own home, was the seed of everything that followed. Yves Rocher founded his company in 1959 on an idea that ran against the grain of its time: that plant biology and dermatology could be brought together to create skincare that actually worked. To deepen the science, he partnered with dermatologists. He founded CERCO, the Centre d’Études et de Recherches Cosmétiques, laying the groundwork for what the brand now calls dermobotany, skin physiology and plant knowledge treated as a single discipline. In the town of La Gacilly, there is also the Maison Yves Rocher, the brand’s immersive museum. Its five rooms walk visitors through the company’s story, sense by sense. images courtesy Yves Rocher Into the Living Laboratory That founding conviction is easiest to see at Yves Rocher’s pilot centre in agroecology, just outside La Gacilly, a working botanical garden that doubles as a research station. The site serves three purposes, its resident agronomist and botanist, Cécile L’Haridon, explained as we walked the plots. The first is production: growing the brand’s own plants organically, then processing them into the active ingredients that give its formulas their effect. The botanical garden itself is almost a manifesto, a visible, walkable version of the belief that plants belong in the cosmetics business, not just in its marketing. The second is innovation. ‘We try to imagine what tomorrow’s plants inside our cosmetics will be’, L’Haridon said, not just which new actives to develop, but which plants will even be possible to grow as the climate shifts. Nothing here is irrigated. Crops are chosen for drought resistance from the outset, and water is given only in narrow windows, just before blooming, in small amounts, if a heatwave threatens the flower itself. The third goal is harder to name in English. L’Haridon called it ‘influence’, but it’s closer to community: partnerships with local farmers, naturalists, and academic researchers, built on shared observation and shared science. Agroecology, she said, is too complex to figure out alone. photography Sandra Myhrberg Between the rows of plants destined for cosmetics, other crops such as phacelia and buckwheat are deliberately sown as living soil cover, plants that will never end up in a bottle. They pull different nutrients from the ground and then return them, building fertile, water-retentive soil that lets the ‘real’ crops survive a dry summer. Hedgerows thick with oak are managed the same way as corridors that let biodiversity move through the farm and give beneficial insects somewhere to nest, insects that then protect flowering crops like marigold and cornflower from disease. Two colleagues were at work in one plot, marking test rows with orange stakes and recording plant behaviour that will later become the statistical case for exactly how much a cover crop helps the cash crop growing beside it. ‘When we work on a new plant’, L’Haridon said, ‘we want a strong active with strong benefits for skin, and we want the plant to be able to manage present ecological pressures. Commitment and efficacy – these are our two goals’. A Walk Through the Garden The garden holds surprises even for a genus as familiar as chamomile. Yves Rocher grows both German and Roman chamomile side by side – visibly different plants – and the German variety, prized as a strong soothing agent, is what goes into skincare and makeup. From a single flower, L’Haridon’s team extracts three distinct botanical actives depending on the method: oil, supercritical CO2, or a botanical water, each pulling out different compounds. ‘It’s so rich’, she said. ‘A never-ending story’. photography Sandra Myhrberg Nearby grows the ice plant, Mesembryanthemum crystallinum, its leaves studded with water-filled vesicles. It can survive drought, salt, and blistering sun by shifting its metabolism, synthesising energy at night and adjusting output as conditions change. ‘If you can live in the desert, you are the future plant’, L’Haridon said. It’s the base of the brand’s anti-ageing Lift range. Its close relative, edulis, does something different: its water- and osmolyte-rich leaves make it a powerful moisturiser, the base of the Hydra range, which claims to hold skin hydration for 100 hours. The team even developed a specific cultivation method, which L’Haridon called a ‘technical itinerary’, to increase leaf surface area and boost the concentration of active compounds inside it. Cornflower shows how differently the same plant can be treated depending on its end use. Machine-harvested, the stem and leaves come with it; picked by hand, it’s flowers only, and it takes four hours of hand-picking to gather a single kilo, destined for the brand’s Pur Bleu cleansing range. Marigold follows a similar logic: sown after a season of soil-building cover crops specifically to concentrate its potency, with the surrounding hedgerows and plant covers studied for their direct effect on how powerful the resulting active turns out to be. Ask L’Haridon for a favourite, though, and she doesn’t reach for any of the showier plants. ‘Have you heard of phacelia?’ Modest-looking and little known outside the industry, it’s
