Evaluation of autumn aster sympphyotrichum novi-belgii in the conditions of central Europe thermophitics
Ing Pavel Komárek
Species Symphyotrichum novi-belgii is valuable for many reasons, mainly for colour and abundance of flowering that occurs in autumn season, but equally for its hardiness and vigorosity. Currently, there is around 300 cultivars available on the market, but despite of the abovementioned hardiness and vigorosity, not all these cultivars are suitable for conditions of central Europe region. The aim of two-year field experiment was selection of suitable cultivars for central Europe region, based on evaluation of morphological and physiological traits of 20 cultivars.
