BACKGROUND:Alexandria Park Community School, in inner Sydney, is a green oasis in the middle of the industrial sprawl. The school, with its large indigenous student base, asked Costa to help them build a bush tucker garden to be used as part of the school curriculum.
Bush tucker gardens are starting to gain popularity, along with kitchen gardens (all hail Stephanie Alexander). They do require a bit of work to ensure the plants being used will actually grow in the area; there's still a prevalent feeling that native plants, like the indigenous human population, are consistent over Australia and that a lillypilly will grow in central Australia (hint: it's a rainforest plant and like neither frost nor drought).
I approve of Costa's list for this Sydney garden, however :)
