Present and perspective cultivars of Syringa L. for greening the city of Novosibirsk

Abstract

There is a need to correct a historical imbalance of ornamental shrubs and, in particular, hybrids and cultivars of genus Syringa L. in the city of Novosibirsk. Recent ambitious projects of reconstruction of the present green areas and creating the new ones have enhanced the relevance of testing the cultivars which have been conducted at the CSBG SB RAS for 35 years. In order to study further the features of biology and freeze resistance under continental climate of the south of West Siberia, CSBG’s collection was completed with 54 new samples of cultivars of genus Syringa from 5 botanical institutions and nursery gardens located in the different climatic zones.
