This book is a good introduction to the prostantheras. A large number of species are described in their natural habitat so the reader can appreciate the conditions and terrain in which the species grow. When you read, for example, that Prostanthera lasianthos is a lover of coolness and moisture and grows in deep cool gullies, there is no way you would plant that species in the hottest, driest spot in your garden, is there? This has more meaning than "plant in the shade", doesn't it? For me this is one of the strengths of the book....the plants are so firmly located in their natural surroundings.
The book has delightful coloured photos of each species described, as well as detailed line drawings. There is a helpful glossary of botanical terms and a Key to the recognised species of Prostanthera to aid identification. At the back of the book - Chapter 21 - there is an alphabetical list of all the species described in the book, each listing incorporating a short description of the plant, the geographical locations where it occurs and page references which make it very simple to turn to the text for more information on the plant. The book also contains a list of then-known garden cultivars, a chapter on the oil content of the leaves of mint bushes and possibilities for commercial exploitation and a short chapter on propagating and growing them.
This is a nicely presented book which contains a wealth of information. It is written, as the author says, with the eyes of a lover. The language is lyrical and colourful, rather than scientific and some readers may find it wordy and the writing somewhat flowery. However, it is a book to browse through, savour and enjoy. It is written by a man with an unerring eye for the beauty of the plants, who became a recognised expert in the genus and who had an ability to communicate his enthusiasm and pleasure to the reader. It is said the best teachers are not those who just impart the facts but those who arouse enthusiasm for their subject. If you will take the time to travel a while with George Althofer, I don't think you will ever pass by a Prostanthera again without pausing.

Ours is one of eight species - six in Madagascar and the other in sub Saharan Africa. She presents different hypotheses for its mysterious arrival in Australia.
The author, who lives in West Kimberley, says old Boab's are "less like a tree than a woody village" with hollows and cavities sheltering vertebrate life - birds, bats, goannas, frogs - plus invertebrates. For her the Boabs "became an obsession, almost a secret vice", as she recorded all her activities, observations and research in notebooks.
Boabs show a marked contrast between dry seasons, when their branches are bare (as most tourists see them), and wet seasons when they're covered with rich green foliage. The beautiful flowers open at night, possibly pollinated by hawk-moths. Pat Lowe describes the unusual fruit, wood and bark, and their many traditional uses for food, rope or string. Many individual trees have such character they are known almost as personalities, each with its own history.
If you are already as intrigued by these wonderful trees as I am, Pat's enthusiastic writing is a delight. If you haven't been to the far north-west and seen Boabs at home there, standing proud in their special environment, this book will give you an insight into their fascination.

While this book is written for Victoria, the principles can be applied across Australia. It contains details on conserving water, environmental and health issues to do with used water, site assessment for re-using water, re-using water on the garden, re-using water to flush the toilet, septic tanks, constructed wetlands, aerobic treatment systems and composting toilets.
The water uses of the average house is: kitchen 8%, laundry 24%, bathroom 38% and the toilet 30%. To put that in a better perspective the 'average' Melbourne house produces 160,000 litres of used water in a year, so there is plenty of scope to re-use some of this water.
The two main re-use opportunities for used water are to use it in the garden, or to use it for toilet flushing. Toilet flushing with used water can be a permanent re-use opportunity, watering the garden with used water may be a seasonal opportunity. The major limitation to using it on the garden is the type of detergents, bleaches, disinfectants and soaps that you use, as use of the wrong ones will lead to a build up of sodium and potassium salts in the soil which can change the pH and also lead to a breakdown the soil structure especially in clay soils.
This is a very practical book containing all you need to know on this topic! All you need to add is your enthusiasm and dollars to make it happen and help save a valuable resource.
