WALL GARDENING ON COASTAL AREAS ON THE EXAMPLE OF THE RESORT AREA “IMERETINSKY” (SOCHI)

The humid subtropical region of Russia covers the eastern Black Sea coast, the resort city Sochi is exactly here, geographically located between the Republic of Abkhazia and the Tuapse district of Krasnodar Territory. There are several natural and climatic zones in Sochi area – coastal, foothill, mid-mountain, high-mountain and alpine zones. With regard to growing ornamental woody vegetation, the coastal zone is of the greatest interest, which is a favorite vacation spot for residents and guests of the resort. In landscape design for coastal territories, a special place is occupied by wall gardening, i.e., the use of various types of lianas, which allows, while saving soil resources, to obtain the maximum ornamental effect from plantings. The park area in the Resort area “Imeretinsky” is located on the first coastline of the Black Sea in “Imeretinsky” lowland. The total range of tree and shrub vegetation in this object includes 123 species (varieties, garden forms), from which 25 have the life form of lianas. Based on the taxonomic analysis carried out within the collection, ornamental lianas growing on the landscaping object are assigned to 11 genera, 9 families, and include 15 garden forms and one natural variation. The assortment is represented by evergreen (semi-evergreen) and deciduous species, balanced by the terms and duration of flowering. All cultivated lianas are resistant to the main limiting abiotic factors on the coastal zone (high temperatures of the air and soil layer, intensive insolation regime, predominance of clear and cloudy days over cloudy ones during the year, increased content of salt particles in the air) and are damaged to a low degree by pests and diseases. A wide range of adaptive species provides a long-lasting ornamental effect on the object with obvious space savings.
