This 200-acre urban garden is best visited during spring, when it's covered in roses, azaleas, bamboo, and orchids. Do visit the penjing garden; penjing translates as "pot scenery" and describes the Chinese art of creating a miniature landscape in a container. More than 2,000 bonsai trees line the penjing garden's courtyards and corridors. The Chinese cymbidium garden has more than 300 varieties. Within the Grand Conservatory are towering palms and more than 3,000 varieties of tropical plants.
