Comprehensive Evaluation of the Ornamental Traits and Adaptability of Three Cold-Tolerant Hydrangeas in Beijing
In order to provide a scientific reference for the cultivation,planting and garden application of hydrangea in North China,a multi-index survey on the ornamental traits and cold tolerance adaptability of hydrangea was carried out,and its application effect was analyzed.Through the Beijing Zoo's Hydrangea macrophylla'Endless Summer',Hydrangea areborescense'Annabelle'and Hydrangea paniculata'Vanilla Strawberry')three hydrangea varieties were tested for cold tolerance in the open field.The cold tolerance adaptability indicators such as germination rate and survival rate of plants in the following year,the number of flowers in the full flowering period,and the flowering period and other ornamental indicators were recorded and evaluated.The results showed that the three hydrangea varieties could safely overwinter in Beijing,but there were still some differences in ornamental and cold-tolerant adaptability,and the cold-proof measures of hydrangea had an impact on the adaptability of hydrangea,which was necessary to improve the wintering performance.Hydrangea macrophylla'Endless Summer'had the highest overall score and had strong ornamental traits and adaptability,followed by Hydrangea areborescense'Annabelle'and Hydrangea paniculate'Vanilla strawberry'.In the future,it is necessary to strengthen regular monitoring of hydrangea in the park,screen for advantageous species,summarize structurally stable community configuration models and maintenance management methods,and enrich the selection of green plants in the park.
