Qionghuapu 瓊花譜 is a book on the Chinese snowball (Viburnum macrocephalum) written during the late Ming period 明 (1368-1644) by Yang Duan 楊端 (c. 1600), courtesy name Weizheng 惟正, from Yinxian 鄞縣, Zhejiang.
The brief book quotes from older sources on the plant, presents important prose and lyric texts, and describes various kinds of the flower. The text begins with a quotation of Du You's 杜游 Qionghuaji 瓊花記 from the Song period 宋 (960-1279), for which reason Du You was by some scholars seen as the author of the book.
The book catalogue Dushu minqiu ji 讀書敏求記 calls Yang's book Qionghuakao 瓊花考, while the catalogue of the Tianyige Hall 天一閣 calls it Yangzhou qionghua ji 揚州瓊花集.
