The Japanese garden is alive all year round, and visitors will find something new every week. Towards the end of winter, when clouds of mist rise from the surface of the water between still-bare trees, pink and red camellia blossoms and the strange yellow-brown strands of witch hazel (Hamamelis) impress the visitor. Soon after it is the turn of the magnolia, which also originally came from China, along with tulips, narcissi, hyacinths and other heralds of spring - a symphony of scents and colors.
The ginkgo is regarded as a plant “fossil”: with its fan-shaped lobed leaves, it is an intermediate stage between coniferous and deciduous trees, and has been in existence in its present form since the Early Jurassic period. It may well be the oldest living plant species on earth. The lofty ginkgo, with its pale green leaves that turn a golden yellow in autumn and drop within a few days, is the very epitome of an East Asian tree for many Europeans. So the garden still fulfills the purpose which its creator had in mind when he laid it out between 1912 and 1914: to show the observer the cycle of nature on a small scale, just like in East Asia.
