An easy to use colour coded field guide to the wildflowers of the Adelaide Region. Most flowering plants from the tiniest orchids to the tallest trees are drawn, a total of over 1400 species. While many botanical books are very technical, It's Blue with Five Petals is essentially a picture matching book. The flowers are illustrated and grouped by their colour, flower shape, and general size or growing habit. It is written for people without a horticultural or botanical background and will be useful for students and land managers. It's Blue with Five Petals shows all the common plants of the Mount Lofty Ranges, the surrounding western and eastern foothills, and northern Adelaide Plains, the Barossa, and the Fleurieu Peninsula from Cape Jervis to the lower lakes of the River Murray.
