A study of the growth features and structure of shoots of species of the Viburnum L genus was conducted. Determination of features of the structure of shoots of species of the Viburnum genus is relevant because there are substantial differences in the structure and dynamics of growth within the genus. The study of the dynamics of shoot growth was conducted according to the method of A.A. Molchanov and V.V. Smirnov (1967). The studied species belong to three sections of the Viburnum L. genus. In the species of each of the sections, the features of the bud structure largely determine the structure of shoots. It is determined that the species of each of the three sections of the genus have a special structure of shoots. The rhythms of growth and development of plants of native and introduced species of the Viburnum genus are studied. The timing of shoot growth of species of the Viburnum genus is analysed, and the length of annual shoot growth is determined. Phenodates of the beginning and end of shoot growth were established. It is identified that the onset of individual phenophases quite clearly correlates with the sum of effective temperatures above +5°C. For species of the Viburnum genus the following types of shoots are characteristic: tillering, stem, generative. Intensive growth of shoots of all the studied species occurs in May – mid-June. In Lantana section species there are two peaks of shoot growth – May and mid- July. According to the duration of growth, viburnum shoots can be divided into two groups: 1) with a short growth period (65-75 days): V.opulus L., V.sargentii Koehne, V.prunifolium L., V.rufidulum Raf., V.lentago L.; 2) with a long growth period (100 or more days): V.lantana L., V.carlesii Hemsl., V.veitchii C.H. Wright, V.rhytidophyllum Hemsl., V.buddleifolium C.H. Wright, V.burejaeticum Rgl. et Herd. The data obtained indicate that the greatest annual growth of shoots of all Viburnum species was received at the age of 4-7 years. A decrease in the annual growth of axial shoots signals the need for preliminary rejuvenation of the plant
