Walking into the Adelaide Botanical Garden, the roads are lined with plants of various shapes and colors, which are very symmetrical. There is a rose garden not far from the entrance, and the roses of various colors compete for peoples attention. Inside the park, there is a large-scale glass greenhouse "Tropical Rainforest Observation Park" in the southern hemisphere, commemorates the 200th anniversary of the founding of Australia. Walking in you feel as if you were in the Jurassic era. You will run into water sprays from time to time.
