An oasis in the heart of the city, the Adelaide Botanic Garden features beautifully landscaped gardens, majestic avenues and stunning architecture. Spanning 50 hectares, their plant collection is spread across numerous zones and areas that will take you nearly a whole day to explore well. For instance, the Australian Native Garden area showcases innovative and artistic ways of using native plants on a domestic scale. These include examples of native plants used for hedging, structural planting, screening vegetation, as specimen plants, formal and informal garden beds, in pots, and as copses of trees. The 20,000 plants of the First Creek Wetland in the garden’s southeast corner are designed to educate visitors on the importance of wetlands for maintaining healthy environments, especially urban ones. Then there is the majestic Ficus Avenue, where 150-year-old Moreton Bay Fig trees line the path. A cool spot on warm days, you can't help but be amazed by their buttress roots which help stabilise these towering giants of the botanical world. The International Rose Garden has thousands of fragrant and colourful roses that flower from spring to autumn. You can see Australian-bred, single, heritage and pillar roses here.
