One of the most unusual sights in Germany, Mainau is a tiny island given over to the cultivation of rare plants and splashy displays of more than a million tulips, hyacinths, and narcissi. Rhododendrons and roses bloom from May to July; dahlias dominate the late summer. A greenhouse nurtures palms and tropical plants.
The island was originally the property of the Teutonic Knights, who settled here during the 13th century. In the 19th century Mainau passed to Grand Duke Friedrich I of Baden, a man with a passion for botany. He laid out most of the gardens and introduced many of the island's more exotic specimens. His daughter Victoria, later queen of Sweden, gave the island to her son, Prince Wilhelm, and it has remained Swedish ever since. Today it's owned by the family of Prince Wilhelm's son, Count Lennart Bernadotte. In the former main reception hall in the castle are changing art exhibitions.
