Melbourne is often referred to as Australia's garden city, and the state of Victoria is officially known as "the garden state". There is an abundance of parks and gardens close to the CBD with a variety of common and rare plant species amid landscaped vistas, pedestrian pathways, and tree lined avenues. There are also many parks in the surrounding suburbs of Melbourne, such as in the cities of Stonnington and Booroondara, south east of the CBD.
