Oriental gardening skills are among the oldest in the world. Gardens were established in China as long ago as one thousand years BC. They can be understood as landscape pictures, which have rhythm; they avoid symmetry and combine the elements which are seemingly not connected but as a whole they act in a balanced and harmonious manner.Indispensable components of oriental gardens are "mountains" because the Chinese always admire and respect them. Stone hills and selected stone obelisks symbolise them in the gardens.
An integral part of these gardens are oriental plants, which include Chinese angelica (Angelica chinensis L.), balloon flower (Platycodon grandiflorum (Jacq.) A.DC), Baikal skullcap (Scutellaria baicalensis Georgi) and trees such as black pine (Pinus nigra Arnold), ginkgo (Ginkgo biloba L.) or Chinese dawn redwood (Metasequoia glyptostroboides Miki ex Hu & WC Cheng).
