- Аннотация: The objects of the study are 13 varieties and species of the genus Hydrangea L, which were planted in the collection of the Department of Plant Introduction and Acclimatization, UdmFRC, Ural Branch of the Russian Academy of Sciences, Izhevsk, in 2017. Representatives of the genus Hydrangea are ornamental flowering shrubs. Due to insufficient knowledge of bioecological features, species and varieties of representatives of the genus Hydrangea in the Middle Cis-Urals are still rarely used. The aim of the research is to study the bioecological features of new for the region species and varieties of representatives of the genus Hydrangea for the prospects of introduction in the conditions of the Middle Urals. The paper presents the results of phenological observations in the period 2019-2021. according to the main phase for flowering shrubs - the beginning and end of flowering. During the years of research, anomalous periods for the development of plants were revealed during the growing season in the conditions of the Middle Urals and their influence on the flowering of the plants under study. Moisture deficiency during the growing season has a negative effect on the development of plants and on the quality of flowering. An important property for flowering shrubs is the duration of flowering. The longest total flowering over three years of observations is more than 300 days for H. paniculata "Weems Red", H.petiolaris "Petiolaris", H.arborescens "Anabel". According to the results of studies (2019-2021), as promising (I, II group) for green building in the cities of the Middle Urals, 8 representatives of the genus Hydrangea were identified, who scored more than 75 points according to the integral assessment of the prospects for introduction and have good decorative effect: H paniculata "Lime Light", "Pinky Winky", "Diamond Runge", "Weems Red", "Vanilla Fries"; H. serrata "Bluebird"; H. arborescens; H.petiolaris "Petiolaris".
