Abstract: To study the suitability of different Paeonia suffruticosa varieties, after a preliminary screening of 8 famous varieties,studies were made of their growth and flowering characteristics. The results showed that introduced varieties had similar phenology performance to the source area,with good adaptability and normal tillering. Besides, introduced varieties maintained good ornamental values, with same phenotype, such as flower types and colors. Each variety scored more than 10 points in single introduction suitability,and relatively high points(≥ 70)in comprehensive evaluation. It was illustrateed that 8 varieties had a high introduction adaptability, which could be better candidates for further indroduction and domestication studies.
