The Royal Botanic Garden in Sydney opened in 1816, is the oldest scientific institution in Australia, and is one of the most important botanic gardens in the world. It is quite diverse, from the glorious wildflower garden in the first picture, to planned formal gardens, a Chinese garden, and even an extensive palm grove. It is open every day, is free, and is situated along beautiful Sydney Harbour with views of the Opera House.
The first several photos are from around the gardens, including an adorable cross-eyed bird that let us get very close, and even a koala! Following those are photos of the display they had on carnivorous plants, including some great graphics and even a hedge with the theme!
