Mainau "flowering island" in Germany
Mainau is an island in Lake Constance (on the south shore of the Überlinger See near the city of Konstanz, Baden-Württemberg, Germany). It is maintained as a garden island and a model of excellent environmental practices. Administratively, the island has been a part of Konstanz since December 1, 1971, when the municipality of Litzelstetten, of which Mainau was part, was incorporated into Konstanz. Mainau is still part of Litzelstetten, now one of 15 wards (administrative subdivisions) of Konstanz. The island belongs to the Lennart Bernadotte-Stiftung (English: the Lennart Bernadotte Foundation), an entity created by Prince Lennart, Count Bernadotte af Wisborg, formerly a Prince of Sweden and Duke of Småland. It is one of the main tourist attractions of Lake Constance. Beside flowers there is a park landscape with views on the lake. There is also a greenhouse with tropical climate and thousands of butterflies.
Mainau is a "flowering island" notable for its parks and gardens. Frederick I, Grand Duke of Baden, created the island's arboretum, which now contains 500 species of deciduous and coniferous trees, many exotic and valuable, including fine specimens of Sequoiadendron giganteum (1864) and Metasequoia glyptostroboides (1952). The island also contains about 200 rhododendron and azalea varieties.
The Italian Rose Garden laid out geometrically with pergolas, sculptures, and fountains, and includes some 500 rose varieties. The Mediterranean terraces contain exotic pot plants, including palm trees, agaves, cacti, and Bougainvillea. The island as a whole contains about 30,000 rose bushes representing 1,200 varieties, and about 20,000 dahlias of 250 varieties.
