Nice of you to say so, Sam, but no, this garden is only a result of a fluke wet summer. Two years ago we came out of 13 years of drought, so bad that farm dams were not filled, only house dams, via a channel system, and with the storages locally down finally to about 3% capacity. During the drought I had no grass at all at times, just bare dirt where I exercised my dogs. Then Queensland got a wonderful wet season which sent flood waters down through the centre of Australia to fill Lake Eyre, and I believed the local plant nursery owner who said that we'd get good weather once Lake Eyre filled, so I guess I've gone on a real spending spree for the garden since the drought broke.
Haven't a clue what will happen next Summer, so I will just enjoy it all while I can.
