The book begins with a game theory on plants, the name of their different parts, etc. Then the work class in a very easy way the plants according to their flower color (white, yellow, blue, purple and green). Should you still decide to eat in summer plants, in which case you will be much more difficult to recognize because the photos are essentially based on the top and it's not always easy to recognize a plant by leaves because the photos are not always very good at this level. I also liked that the plants were scored on their flavor from 1 to 5. The book is very convenient as it is in a small size and thus fits easily in your pocket 'but good, therefore I find that the price is really expensive. I think Couplan works must be better but again, the portfolio is significantly lighter.
