Modern approaches to the use of Berberis Thunbergii cultivars for sustainable landscape design

Abstract

Purpose. For the purposes of sustainable landscape design of the urban space, to substantiate new modern nature-oriented solutions for the use of dwarf cultivars of the Berberis Thunberg species. Methods. Visual assessment, computer modeling and visualization. Results. One of the aspects of realizing the goals of sustainable development, namely Sustainable development of cities and communities, is the rationalization of living space in cities. An integral part of this process is the aesthetic arrangement of territories, which ensures sustainable landscape design. The design of flower arrangements, flower beds can and should change, be updated, absorb new things. One of the ways of realizing such a context when creating permanent flower beds is the use of metal frame structures, which solve the task of creating a contrast with the colors of decorative plant compositions. The choice of the color of the metal frame should be subject to the thematic and landscape context. In order to give graphicness to decorative plant compositions from cultivars of Berberis thunbergii species, the expediency of horizontal contouring of the plant ornament with metal structures with a width of contour lines of 3–5% of the linear dimensions of the structure is shown. Modeling of structures was carried out using the program Realtime Landscaping Architect 2023.02, Trial Free Version. The use of the color solution, shape, texture of the modeled structures, the use of contour lighting of the decorative-but-foliage installation is substantiated. Cultivars of Berberis Thunberg are given, which are appropriate for use, the life span of which can reach 50 years under the conditions of performing the necessary minimum care. Conclusions. The creation of permanent, aesthetically expressive flower beds and flower beds involves not only the use of environmentally friendly materials, but also the choice of local or adaptive decorative cultivars that provide all-season decorativeness, the absence of the need for annual renewal of plant material, artificial watering, and the creation of a habitat for pollinators and birds The use of cultivars of the Berberis Thunberg species contributes to the creation of stable flower beds that are able to preserve their decorative characteristics for a long time. The most harmoniously proposed compositions will be revealed in the presence of dynamic visual points, a deep perspective and a panoramic view.
