The article is devoted to the study of phenophases of Syringa sweginzowii Koehne & Lingelsh. = Syringa tomentella subsp. sweginzowii and Syringa komarowii C.K.Schneid. section Villosae C.K.Schneid in the collection of the Botanical Garden of the Ural Branch of the Russian Academy of Sciences. The patterns of growth of annual vegetative and generative shoots have been established. The average duration of growth and development of branching shoots is 133 days. Features of the mechanisms of apical growth of vegetative and generative shoots are manifested in the form of differences and similarities in seasonal dynamics. Apical growth has similar seasonal dynamics curves in shape and is characterized by synchrony in all species, which can indicate the similarity of their mechanisms in different shoots. There are specific characteristics in the growth rate of lilacs; of the two species, Zvegintsov’s lilac is characterized by a high rate of apical and radial growth.
