Abstract: There is the site of lianas as a part of the exposition «Fruticetum» in the Botanical Garden-Institute of Volga State University of Technology. It is an area of 0.15 hectares, with 5 rows of metal supports 1.5–3.0 high. Woody plants of 98 names from 14 genera of 10 families grow here: Actinidiaceae, Aristolochiaceae, Bignoniaceae, Caprifoliaceae, Celastraceae, Hydrangeaceae, Menispermaceae, Ranunculaceae, Schisandraceae, Vitaceae. The largest number of taxa in the collection includes the following genera: Clematis – 54 taxa, Vitis – 10, Lonicera – 7. The most widely represented family is Ranunculaceae (56 taxa). The Vitaceae family contains the largest number of genera (3). Cultivars and hybrids have the main share in the collection (62.2%). The cultivars of clematis are the most numerous (42 names). They have a high decorative value and are an undoubted decoration of the site. The low ornamental shrubs and perennial herbaceous plants are planted in the exposition to increase the decorative effect. The article provides information about winter hardiness, growth and development of lianas, as well as the features of agrotechnical measures. The directions of development are presented. These data are of interest to employees of botanical gardens, students of plant-growing directions and amateur gardeners. The materials are accompanied by photographs.
