Long yellow day lily is cultivated in Asia for its edible flowers.

The tubers, inflorescences, buds and flowers can all be cooked and eaten. Dried or fresh flowers, sometimes called "gum jum" or "golden needles" (金針 in Chinese; pinyin: jīn zhēn) or as huánghuācài (黃花菜, literally "yellow flower vegetable") are used in Chinese cuisine for dishes including hot and sour soup, daylily soup (金針花湯), Buddha's delight, and moo shu pork. The dried flowers are also used in Japanese, Korean, Thai, and Vietnamese cooking.[3][4]
