The article is devoted to the study of the growth and development of Syringa species in the collection of the Botanical Garden of the Ural Branch of the Russian Academy of Sciences. Heights of Syringa L. of the Villosae section in various geographical areas are given. Growth indicators of seven-year-old plants of hairy lilac in 7 species were studied. The heights, volume and area of the crown projection were measured, the number of formation shoots (skeletal branches), the number of generative shoots and branching shoots of the 1st order were calculated, and the length and diameter of branching shoots were measured. Differences between the studied species are already significant at an early age. The best indicators were found in S. sweginzowii Koehne et Lingelsh. (h-1.51 m, number of branching shoots 218, generative shoots - 28); S. Henry Schneid. – 1.43; 193; nine; S. villosa Vahl. – 1.36; 140; 17; S. tomentella Bur. et Franch. – 1.33; 159; 13; S. komarovii Schneid. - 1.07; 133; 10; S. velutina Komar. – 1.25; 119; eleven; S. wolfii Schneid. – 1.15; 23; 8. The beginning of flowering was noted at the age of 5 in S. sweginzowii, other species from
