Abstract

Abstract: In order to understand the growth and flowering status of different peony varieties （Paeonia suffruticosa Andr.） combinations in Wuhan area, the flowering period and biological characteristics of five introduced peony varieties （Zhongyuan, Jiangnan, Japan, the United States and Francepeony cultivar group） in Wuhan were observed and studied from 2017 to 2019. Results showed that the flowering period of different peony cultivarswas mainly concentrated in April in Wuhan area,and the peak flowering was early and middle of April. There were also some differences in the flowering period of different peony cultivars in the introduced land. In addition, both planting foreign peony cultivars and domestic peony cultivars in the same garden could extend the flowering period by 10~15 days, and at the same time enriched the color of peonygarden. Compared with the place of origin, the peony color basically maintained the original color, but the flower shape was degraded. There were 44 % of foreign peony cultivarswhose flower shape showed degradation to different extents.

Key words: peony （Paeonia suffruticosa Andr.）, flowerstage, biological characteristics, Wuhan city
