Background. The Chinese juniper, Juniperus chinensis L., is widely used in landscaping and is the source of many other species and cultivars, including J. x pfitzeriana. Numerous ornamental varieties of J. chinensis differ in height, crown architectonic and leave color. Evaluating the ornamental features of plants, such as plant size, color scheme and other characteristics, is necessary for their successful when creating a decorative composition. Thus, this study was aimed at analyzing the decorative features of J. chinensis cultivars commonly used in greening in the South of the Kyiv region.
Methods. Four techniques for assessing the decorativeness of plants were used, which are modifications of the generally accepted method of O. Vynohradova and N. Kotelova for studying the ornamental features of conifers, or even exclusively of junipers.
Results. J. chinensis 'Spartan' obtained the highest coefficients of decorativeness when applying all four methods. The tall-growing J. chinensis 'Stricta' and the medium-growing J. × pfitzeriana 'Pfitzerana Aurea', 'Old Gold', 'Gold Star' showed the highest ones when defined by three methods, and the tall-sized J. chinensis 'Blaauw', J. × pfitzeriana 'Mint Julep', the medium-sized J. shinensis 'Shimpaku', J. × pfitzeriana 'Pfitzeriana Glauca', 'Saybrook Gold' and all short-growing cultivars - by two methods. J. × pfitzeriana 'Pfitzeriana', 'Pfitzeriana Compacta' and J. chinensis 'Plumosa Aurea' were praised when only one method was applied and so they are significantly inferior to other cultivars in their ornamental qualities.
Conclusions. The complex use of various methods for determining the decorative qualities of J. chinensis cultivars made it possible to determine the most ornamental of them for their further use in landscaping.
