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.

Highlights

Vegetation on these territories is thickened, ornamental shrubs still remained there are in poor state due to the lack of regular and adequate plant care

Summary

Introduction

The city of Novosibirsk is experiencing the shortage of ornamental bushes despite quite big green fund. Reconstruction of the current green areas and creation of the new ones started 5 years ago and revealed the need for modern assortment of ornamental bushes, and, first of all, reliable and tested cultivars of common lilac and hybrids of Villosaea Group. Current offers of these plants are disproportionate to the quantity and quality of planting material (there are not many checked and confirmed cultivars and there are not enough seedlings of standard size).
