Another place where natural history and education are combined is the Giardino Esperia, established by the Modena section of the CAI (Italian Ramblers' Association) at Passo del Lupo, at the foot of Mount Cimone, 1500 metres above sea level. This garden of three hectares, with its adjoining park with benches, stone-paved paths and small bridges, contains a cafe, a beech wood, beds of alpine flowers (including edelweiss), many species of flowers found on the surrounding mountains, and herbs. Open from mid May to the end of September, the garden offers special attractions throughout the summer months, from the crocus in early May and the globeflowers and gentians in the middle of the month to the orchids in mid June, the mountain thistles and saxifrages in mid August, the poisonous berries and delicious redcurrents and sorbus fruits in mid September, and the bilberries, strawberries and raspberries. Of course there are also times when no spectacular flowers are in full bloom, but visitors can console themselves by visiting the herbarium, a real garden within the garden, where well preserved flowers of various species are always on display. The most special feature of the Esperia is its practice of providing full details about every species present, including its scientific and common name, habitat, flowering time and pharmacological properties, as well as any interesting folk traditions concerning it. Many plants and flowers are accompanied by signs carrying quotations from poems about them. A visitors' route with signs in braille for the visually impaired was established in 1989.
