Bushtucker gardens

A bushtucker garden is one that contains indigenous plants used for culinary, and sometimes medicinal, purposes. It can be designed in almost any garden style, by choosing edible plants that can suit, for example, formal settings or a sun-loving cottage garden. Species used range from small plants, such as Blue Flax-lily (Dianella caerulea) to large trees, such as Illawarra Plum Pine (Podocarpus elatus).  Different parts of the plants used include fruit, shoots, bark, leaves, roots, tubers or sap, depending on the species. These gardens can be beneficial to birds and other animals as well as humans.
