The paper keeps up to date the problem of development of the wood species assortments flowering in the dry and hot period in the South of Russia. When creating long flowering gardens we usually use a limited number of species which bloom in summer and autumn – these are cultivars and forms of the genus Rosa sp., Budlea sp., Spirea sp. and others. Economic and biological potential of Campsis as a valuable ornamental crop is not fully disclosed. Since 2014, 8 cultivars and forms of Campsis radicans (L.) Seem. and 6 cultivars of Campsis × Tagliabuana (Viss.) Rehd have been introduced in the North Caucasian Federal Research Centre for Horticulture, Viticulture, Winemaking (Krasnodar). For the period 2014–2018 the most promising cultivars combining valuable decorative features and adaptability in the genotype were identified. The best characteristics were found in Campsis radicans cultivars: ‘Apricot’, ‘Flamenko’, ‘Flava’, f. praecox. Drought resistance and winter hardiness in the selected cultivars were equal to 4–5 points. Among the cultivars of Campsis × Tagliabuana stood out: ‘Madame Galen’, ‘Indian Summer’, and ‘Summer Juss Gold Trumpet’. Drought resistance and winter hardiness were lower than those of Campsis radicals, but this does not limit their use in landscaping. The selected cultivars of Campsis will replenish the range of highly ornamental species of summer and autumn flowering period.
