120 cards enable you to quickly identify the 120 most important trees and shrubs. The descriptions will help you to better maintain the plants, understand their growth requirements and buy new plants that are suitable for the site in question. Regardless of whether you want to take the cards with you to buy a specific plant, or whether you're a trainee or a student in the tram or train who quickly wants to bone up on a few details - the practical box will even fit into your trouser pocket.
