Giardino Botanico Alpino Saussurea

Spread across the mountain saddle of the Pavillon du Mont Fréty at 2,173 metres, the Saussurea garden is described by the regional tourism institution as the highest botanical garden in Europe. Beside the Skyway Monte Bianco's intermediate station, it cultivates hundreds of alpine species in the high-altitude conditions where their wild relatives grow.

Why it matters

Saussurea does what no valley garden can: it grows alpine flora at the altitude and in the climate the plants actually come from. Created in 1987, it has grown from a tourist curiosity into a scientific institution — the Fondazione Saussurea, which runs it, promotes naturalistic study of the Aosta Valley and the Mont Blanc area, exchanges seed with other institutions through its index seminum, and collaborates with the region's other alpine gardens. The garden sits within the Pavillon du Mont Fréty nature oasis of the Espace Mont-Blanc, so a visit doubles as an introduction to the high-altitude habitats of the entire massif, from moraine scree to acid pasture.

What to notice

The garden is divided into two contrasting zones. Artificial rockeries group plants by geographic origin, while another area preserves alpine pasture and its spontaneous species. Together they present alpine floras from different mountain ranges alongside plants of the local habitat. The garden's name works on two levels — it honours the plant Saussurea alpina, which itself commemorates the Geneva scientist Horace Bénédict de Saussure, counted by the regional card among the promoters of the first ascent of Mont Blanc in 1786. Beyond the fence lines, the saddle lies between glacial and moraine landscapes; the garden's species lists reflect plants naturalised on the surrounding slopes.

Context and history

The garden was inaugurated in 1987, adjacent to the intermediate station served by the historic Mont Blanc cableway from the mid-twentieth century until its replacement by the Skyway Monte Bianco in 2015. Its scientific role deepened with the establishment of the Pavillon du Mont Fréty nature oasis within the Espace Mont-Blanc, the cross-border cooperation area around the massif. The Fondazione Saussurea, a non-profit ONLUS headquartered at the Pavillon, now manages the site; its published mission covers the promotion and diffusion of naturalistic studies with particular focus on Valle d'Aosta and Mont Blanc, and it maintains exchanges with the Aosta Valley's other alpine gardens, including those at Castel Savoia, Chanousia and Paradisia. The garden cultivates hundreds of alpine taxa across roughly 7,000 square metres.
