As a huge fan of 'The Gourmet Gardener' by Bob Flowerdew, I ordered this book and it too would have received 5 stars from me because it also contains a wealth of useful information (e.g. advantages and disadvantages of different varieties, companion planting).
However, the more I read it in detail, the more frustrating it became. For example, the section on garlic listed just three varieties - Oz Garlic Rosea, Oz Garlic White and Aussie White - instead of referring to the four colour types of white, rose, violet and red and their differing characteristics. Similarly, the sections on both potatoes and apples referred to common varieties in Australia - which is not much use to me in Northern Europe! All became clear to me when I read 'The Yearly Calendar' on page 616 which referred to July (Midwinter), January (Midsummer) etc. The edition supplied to me (on Jan 08) was published in 2006 in Australia.
Therefore just one star for this edition. Amazon have been very helpful and explained that the UK edition is not currently available. I look forward to being able to buy it when available but cannot recommend the Australian edition.
