Giardino Botanico Alpino "Rezia", botanical garden in Italy

The Giardino Botanico Alpino "Rezia" is a 1.5-hectare alpine botanical garden in Bormio, inside the Stelvio National Park, at about 1350–1400 m above sea level. It is arranged in three parts: 1300 species native to the park, shown in habitats such as detrital areas, pasture, sub-alpine bogs and scrub; species collected from the Andes, Apennines, Caucasus, Himalayas, Pyrenees and the Arctic and Antarctic; and a scientific collection ordered by genus.

The garden opened in 1980, according to the English sources, or in 1982 according to the Italian ones, at about 1,350–1,400 m above sea level in Bormio. Since 1996 it has been managed by the Consorzio del Parco Nazionale dello Stelvio. It belongs to the Rete degli orti botanici della Lombardia and to the Associazione internazionale giardini botanici alpini.

The garden is named after Rezia, the historic Raetia region of the central Alps. Since 1996 it has been run by the Consorzio del Parco Nazionale dello Stelvio, and it belongs to the Rete degli orti botanici della Lombardia and the international association of alpine botanical gardens. Visitors can see beds grouped by habitat, such as detrital areas, pasture and sub-alpine bogs.

The garden is free to enter and located in the town of Bormio, about 5 minutes by car or 25 minutes on foot from the town center. The paths are easy to follow and invite leisurely walks, with signs describing the plants along the way.

The garden's scientific collection is arranged by genus rather than by habitat, grouping together plants that share botanical kinship but come from the Andes, the Caucasus, the Himalayas, the Pyrenees, the Apennines and the Arctic and Antarctic. The garden sits at about 1350–1400 m above sea level and covers 1.5 hectares.
