Abstract: The word kokedama consists of the Japanese words "koke" (moss) and "dama" (ball). Due to its easily accessible materials and easy construction, it has become an application that almost everyone can do, and its use is expected to become widespread. The aim of this study is to investigate the differences in the spatial perceptions of designers who have received basic design education in different faculties in the case of interiors that including kokedama. To measure the differences in spatial perception, photographs of 8 different public interiors were processed and a survey was administered to the subjects. The survey results were analyzed statistically. According to the results of the study, the increase in the value of the perceptibility and simplicity criteria also increases the value of other criteria. As the value of perceptibility and simplicity increases in kokedama applications, the perception of complexity decreases. This data explains that the use of kokedama contributes positively to spatial perception. The criteria that have the most effect when they are together are the structure/identity and perceptibility criteria. The highest scorers on the criteria affecting spatial perception were graduates of the faculty of fine arts, while the lowest scorers were graduates of the faculty of agriculture. Keywords: Design, Interior, Kokedama, Spatial perception. 1. Introduction Plants that are taken from their natural environments and placed in pots/containers or plant environments and that can continue their lives in indoor spaces similar to their growing and development environments are known as indoor plants. While these plants appeal to our senses with their features such as size, form, color, texture, smell and seasonal change, they also functionally become indispensable design elements in designing dynamic and more livable interior spaces [1]. People living in big cities spend at least 80-90% of their lives in indoor environments [2]. Urbanites living in a dense and congested urban fabric long for nature and greenery. These people, who spend most of their time indoors, have started to use indoor plants in building blocks for their green needs [3, 4, 5]. Plants are the elements that create the unique identity of the interior. The aim of interior design with plants is to organize livable spaces for plants and functional and aesthetic spaces for people, provided that they use various features of plants by treating plants as architectural elements [6, 7]. In this respect, the presence of plants that provide our connection with natural environments indoors and have the feature of improving the quality of space becomes important [8]. With a planting design activity carried out in the interior, it is possible to create attractive spaces by taking advantage of the design features of plants such as texture, color, line, size and form [9]. This contribution of plants emerges thanks to their characteristics such as leaves and flowers [10, 11]. Research conducted in recent years reveals the importance of indoor plants for human health. It has been determined that it has effects on personal health, creativity, autonomous stimulation, stress management, self-renewal and perfForestryce enhancing effects, especially in the work environment [12, 13]. Researchers also mentioned that office environments with plants are generally perceived as more attractive [14, 15, 16].
