In the shade of beautiful trees in May and partly in June, almost 230 varieties of rhododendron transform the eastern slope of the island of Mainau into a colorful sea of flowers on the eastern slope. The area in the bank area, through which the Rhododendronweg leads, includes all imaginable forms of rhododendrons on around 3,000 square meters, from the flat-growing, dwarfed to the strong-growing with enormous individual flowers to the filigree, deciduous, small-flowered species, usually referred to as azaleas become.
The high humidity of Lake Constance allows the mostly evergreen shrubs to thrive particularly well. The penumbra due to the large false cypresses, trees of life and mighty deciduous trees such as beeches and linden trees is also advantageous.
The colorful ambassadors of Asia include not only common ones, but also unusual and popular varieties. Many rhododendrons have grown into tall, almost tree-like shrubs. Together they form an ensemble of colors with enormous optical depth and a great creative effect.
