| Summary: | Species composition, quantity participation and spreading of ornamental bushes in current system of Novosibirsk green areas are determined. Upper zone (“Verkhnyaya zona”) of Academgorodok is not taken into research as far as it is a cultural heritage site and a significant site of landscape architecture of the 20th century. Special attention is given to participation of lilac species and cultivars (Syringa vulgaris L., Syringa amurensis Rupr., Syringa josikaea J. Jacq. ex Rchb.). It is pointed out that 62 species of bushes are used in the city, including 3 species of lilac, however their quantity participation is not enough and does not satisfy regulatory limits. Twenty six cultivars from the collection Syringa vulgaris L. of the Central Siberian Botanical Garden SB RAS are recommended additionally. Three cultivars, ‘Nadezhda’, ‘Pamyat’ o S. M. Kirove’ and ‘Olimpiada Kolesnikova’, successfully tested in urban environment are highly recommended. Besides, it is recommended to use wider Syringa amurensis Rupr., and to introduce late-flowering Preston hybrids (Syringa x prestoniae Mc. Kelvey (S. reflexa x S. villosa)), curretly absent in green urban areas, in urban greening in Siberia.
