I love this idea! We used to live in Chippendale, just around the corner from Myrtle Street. Myrtle Street is well-known for the produce plantings down the nature strip. All local residents of Chippendale are welcome to share – and are encouraged to maintain – the produce.
However, I don’t walk around our current neighbourhood of Lewisham enough, so I don’t know about places where I could pick local fruit and other useful plants (however, there does happen to be a Bay tree outside our house that is a free-for-all!). If you know about local plants that can be shared — be they lemon myrtle (great in tea!), fruits, or other delicacies please share with us all by leaving a comment below!
