The dominant natural tree of the Valley, within and surrounding the Park is Marri. Other naturally occurring large trees are Jarrah and flooded gum. The Jarrah was once significant but has been logged at least twice now and plays a minor role in the bushland around Araluen. These and the mature exotic trees create an essential framework for the gardens. The rich bark textures, foliage shapes, seed capsule and fragrances of the flowering varieties is a discovery for the senses. The trees emerging in the Park and includes ornamental blossom trees like Springtime cherry, Magnolias, ornamental pear, apple, and flowering plums, through to Crepe Myrtles and flowering Rhododendrons. They put on a delightful display of colour throughout the year.
