Forsythia is one of the most spectacular early-spring flowering shrubs. The genus Forsythia contains 13 natural species and several hybrid ones Forsythia × intermedia Zabel, Forsythia × mandschurica Uyeki., and complex hybrid Forsythia × intermedia Zabel. × Forsythia ovata Nakai.. Three species F. × intermedia Zabel., F. ovata Nakai F. intermedia Zabel. × F. ovata Nakai. were recommended for ornamental gardening in the humid subtropical zone of Russia. Morphological and biological characteristics of 15 varieties of 4 species: F. × intermedia ('Densiflora', 'Golden Times', 'Lynwood', 'Maluch', 'Mikador', 'Primulina', 'Spectabilis', 'Spring Glory', 'Vitellina', 'Week-end'), F. koreana 'Kumson', F. ovata 'Tetragold', F. intermedia × ovata ('Beatrix Farrand', 'Goldzauber', 'Parkdekor') were studied on the basis of the botanical garden "Tree of friendship", "Subtropical Botanical garden of Kuban", arboretum parks "Southern cultures" and "Dendrarium". Early-flowering F. × intermedia 'Densiflora' and F. × intermedia 'Spectabilis' of medium flowering period are recommended as the main varieties for landscaping objects of the Sochi Black sea region. The cultivar with the latest flowering period is Forsythia intermedia × ovata 'Beatrix Farrand'. The distinctive light color shade is noted for F. × intermedia 'Maluch'. The tallest variety is F. × intermedia 'Lynwood', and the shortest variety is F. × intermedia 'Mikador'. As a result of study carried out we made a conclution that it is necessary to continue work on attracting and testing the world assortment of forsythia in the region, as well as to start regional breeding research to obtain the new varieties resistant to stress-factors of region.
