The garden skills of the breeder Otto Eisenhut can be admired in all their magnificence on the brow of the hill between Piazzogna and Vairano, in the Gambarogno Riviera. This botanical garden extends on a total area of more than 17,000 square metres and contains a myriad of plants: approx. 950 different qualities of camellias and nearly as many magnolias, not to mention the azaleas, peonys and rhododendrons surrounded by pine trees, junipers, ivys and fir-trees that are exotic or rare in Europe.
