Corydalis yanhusuo is a perennial tuberous herb from China, grown mainly for its round yellow tuber used in traditional Chinese medicine. Plant the tubers in a cool, well-drained spot and let the plant die back fully after flowering.
Corydalis yanhusuo is a plant species in the genus Corydalis. The Chinese name for Corydalis yanhusuo is yan hu suo (Chinese: 延胡索; pinyin: yán hú suǒ; lit. 'extended barbarian rope'). The Japanese common name is engosaku (エンゴサク) and the Korean common name is hyeonhosaek (현호색). English common names include yanhusuo, corydalis, and Asian corydalis. The tuber of this plant, frequently mislabeled as the root, is an important therapeutic agent in traditional Chinese medicine. It is native to high-altitude grasslands across China including in the provinces of Anhui, Henan, Hubei, Hunan, Jiangsu, and Zhejiang, but is more widely cultivated.
