Assessment of decorative qualities of some species of the spindle-tree (Euonymus L.) during introduction in the Moscow region taking into account seasonal features

The research was conducted to analyze the characteristics and features of different species of the spindle-tree (Euonymus L.) and to assess their decorative properties. In the research, 10 species of the genus grown in the Moscow region on the territory of the Dendrological Garden named after R.I. Schroeder of the Russian State Agrarian University – Timiryazev Agricultural Academy were studied, as well as some other most common species used in landscaping. To assess the decorativeness of the spindle-trees (Euonymus L.), the authors adapted a gradation scale of the decorativeness of woody plants throughout the year, taking into account seasonal features. Decorativeness was assessed taking into account the range of foliage colors, shape, size and texture of leaves, as well as the decorativeness of fruits, which give additional attractiveness to plants in different seasons. The results obtained allow to recommend for wide use those species which, according  to the assessment, have the greatest number of decorative properties. These are the following species: Euonymus latifolius Mill., Euonymus japonicus Thunb., Euonymus europeus L. and Euonymus macropterus Rupr.
