I am enthusiastic about this book is a mine of information. All aspects are covered: history, plant structure, reproduction, classification, rules, tips for choosing, place of culture, culture parameters ... Not to mention 500 species with photos, data sheets and cultivation tips for each. The photographs are of quality, the texts are well written. Species included in this guide are varied and unusual. From my point of view I do not find that good. Congratulations and thank you to the author.
