“Xihu Qiuyun” and “Xianghu Qiuyun” are lotus varieties that have been bred through pollination and crossbreeding methods, with “Xihu Honglian” serving as the male parent and “Qiu Yan” and “Qiu Xing” as the female parents. These varieties are known for their cold tolerance and extended flowering periods. The breeding process, morphological characteristics, biological habits, and propagation applications of these two lotus varieties were summarized and analyzed in this paper, providing a reference for the breeding and application of cold-tolerant and long-flowering lotus varieties. “Xihu Qiuyun” and “Xianghu Qiuyun” were classified as large plant types, and it was found that their blooming periods extend until the middle of October and November, respectively. After being subjected to a second planting, “Xianghu Qiuyun” can have its blooming period extended to December 10th. Flowering periods of 154 and 133 days were observed for “Xihu Qiuyun” and “Xianghu Qiuyun,” respectively. These varieties are characterized by bright flower colors, large petals, and strong adaptability to the environment, and they are considered suitable for widespread use in the construction of wetland parks, river and lakeside landscape greening projects, and the beautification of community water bodies.
