Methodological approach to exhibiting mono-exhibitions of perennial flower crops on the example of the Iris × hybrida Hort collection. in the Nikitsky Botanical Gardens

The article describes a complex approach to designing a monocultural exposition based on the Iris × hybrida hort. collection of the Nikitsky Botanical Gardens. Perennial herbaceous flowering plants are more economically profitable for use in landscaping, and modern cultivars of which are unreasonably rarely used in landscaping on the Southern coast of the Crimea. Currently, the exposition includes 290 cultivars of Iris × hybrida hort. of various garden groups. An analysis of the data accumulated during the period of introduction and cultivar study of the crop in general and for each cultivar of the collection in particular, made it possible to comprehensively approach the designing of the next updated and enlarged exhibition exposition of Iris × hybrida hort. During developing the exposition project, the whole complex of biological and decorative features of this crop was taken into account, which made it possible to ensure the maximum duration of the exposition blooming and its evenness, the proper aesthetic impression, as well as to demonstrate the modern achievements of the hybridization process and its history. A special emphasis was placed on the complex of decorative characteristics of culture. The widest palette of Iris × hybrida hort. colors makes it possible to create color compositions of almost all existing types from crop cultivars: monochrome, complementary, analog, triad, etc. The article describes in detail the process of creating compositions for particular curtains using the main types of color harmonies of the modern color theory. As a result of the research and during the implementation of the project, a methodological approach to the exposition of culture was developed, which can be used by landscape architects to create compositions including cultivars of Iris × hybrida hort., and to design mono-exhibition expositions of other flowering perennial crops.
