(L.) DC., a monotypic species endemic to China and Japan, is an important ornamental shrub. In this study, we reported the complete chloroplast genome sequence of (L.) DC. 'pleniflora' (GenBank accession number: MN418902) to provide genomic resources for its conservation. The total chloroplast (cp) genome is 160,007 bp in length, including a large single-copy region (LSC) of 87,672 bp and a small single-copy region (SSC) of 19,461 bp, which are separated by two inverted repeat (IR) regions of 26,437 bp. The overall guanine-cytosine (GC) content of the genome sequence is 34.0%. The cp genome encodes 132 unique genes, including 84 protein-coding genes, 40 tRNA genes, and 8 rRNA genes. Phylogenetic analysis of 25 cp genomes showed that 'pleniflora' was most closely related to and then had a close genetic relationship with in Rosaceae.
（L.）DC.是一种仅分布于中国和日本的单型物种，是一种重要的观赏灌木。在本研究中，我们报道了（L.）DC.‘重瓣花’的完整叶绿体基因组序列（GenBank登录号：MN418902），为其保护提供基因组资源。叶绿体（cp）基因组全长160,007 bp，包括一个87,672 bp的大单拷贝区域（LSC）和一个19,461 bp的小单拷贝区域（SSC），它们被两个26,437 bp的反向重复（IR）区域隔开。基因组序列的总体鸟嘌呤-胞嘧啶（GC）含量为34.0%。cp基因组编码132个独特基因，包括84个蛋白质编码基因、40个tRNA基因和8个rRNA基因。对25个cp基因组的系统发育分析表明，‘重瓣花’与……关系最为密切，然后在蔷薇科中与……有密切的遗传关系。
