The World Horticulture Expo Garden is 218 hectares in area, 2.5 km in length, and 1.1 km in width. In the garden you can find 5 big exhibition halls (China Hall, the Man and Nature Hall, the Green House, the Science and Technology Hall, and the International Hall), 6 theme gardens (the Tree Garden, the Tea Garden, the Bonsai Garden, the Medicinal Herb Garden, the Bamboo Garden, and the Vegetable and Fruit Garden), 3 outdoor showplaces (the International Outdoor Exhibition Area, the Domestic Outdoor Exhibition Area, and the Exhibition Area for Enterprises), and 2 big squares (Century Plaza, and the Performance Plaza).

The theme of this exposition garden is "Man and Nature, marching into the 21st century". The 34 Domestic Outdoor Exhibition Area is spacious and magnificent. It is home to many diverse gardens from the 31 provinces of China, autonomous regions, municipalities directly under the Central Government, Hong Kong and Macao Special
Administration Regions, and Taiwan. There are two green belts running from south to north symbolizing the Yangtze River and the Yellow River (Huang He). The gardens of the provinces not only display the natural beauty, but also the local culture, religion, and infrastructure of many places. Some typical gardens are the graceful Wanchun Garden (Beijing), the elegant Xiaoxiang Garden (Hunan Province), the modern Bio Garden (Fujian Province), the special Ningchun Garden (Ningxia) and the delicate Shanshui Garden (Guangxi, Shanshui means water and mountains).
The International Outdoor Exposition Garden is a great place for people to enjoy the traditional culture of ancient Asian gardens alongside the ocean culture of European gardens, the harmonious and straightforward immigrant and primitive culture in the American gardens, and the Australian-flavored Oceania Garden.TTT
