Federal State Budgetary Scientific Institution "Russian Research Institute of Floriculture and Subtropical Crops", c. Sochi, Russia Analyzing the light intensity need for the winter garden plants collection in the Russian Research Institute of Floriculture and Subtropical Crops Winter gardens is a picturesque comfortable area for rest and relaxation, which significantly improves the quality of life [10]. The winter garden of the Russian Research Institute of Floriculture and Subtropical Crops can serve as such an example [2]. The objects of research are plants belonging to 39 families, 70 genera and 120 species (cultivars, forms) planted under cover of the Institute [9]. Classification of plants is given in accordance with the electronic catalog The plant list [11]. It is necessary to create a microclimate closest to the conditions of natural growth of species so that plants in the winter garden could be well vegetated, not damaged by pests or diseases, as well as could bloom and maintain their ornamental qualities all year round [1]. Therefore, the entire collection of the winter garden was divided according to the illumination requirements of plants into three large groups, and each species is given a brief description of its origin (table 1). The first group – shade-loving plants. They require illumination of 500-1000 Lux in winter and up to 3000 Lux in summer for successful growth. In the natural environment, these species are located in the undergrowth of dense tropical forests and usually have broad leaves to capture the few sunlight penetrating through the crowns. Their high desire for air and soil humidity is the consequence of this location [5, 8]. The second group – shade-enduring plants. These are mainly middle-tier cultures represented by vines and epiphytes located on the trunks of trees. They also include species growing on the slopes or banks of rivers and lakes.
