This paper aims to analyze the plants compositions of the “Vertical Gardens (Mur Végétal)” by a French botanist Patrick Blanc. The analysis focused on the plants layout drawings which Blanc had sketched by hands when he designs a plant scheme for each project of the Vertical Garden. I have examined five drawings which were published: i) Hotel Pershing Hall in Paris, ii) Quai Branly museum in Paris, iii) 21st Century Museum of Contemporary Art in Kanazawa, iv) Boutique Marithéet Francois Girbaud in Osaka and v) Cité de l’Espace in Toulouse. Following an elaborate work to identify of all the names of plants which were indicated in the layout drawings, I have investigated their characteristics. Accordingly, the species or genus of the plants which were specially preferred to be used in the Vertical Gardens had been revealed. Then, I analyzed the association between the characteristics of the plants and the composition in the drawings. As the consequences, I showed diagrammatically the characteristics of the plants, which are the habitat, growth form, seasonal changes, sun exposure, stratum or vertical strata and so on, have some influences on the composition of the Vertical Gardens, and furthermore I explored the plants compositions of the Vertical Gardens.
