It is the common "ditch" lily, found this on Wikipedia:
Hemerocallis fulva, the Orange Day-lily, Tawny Daylily, Tiger Daylily, Fulvous Daylily or Ditch Lily (also Railroad Daylily, Roadside Daylily, Outhouse Lily, Tiger Lily, and Wash-house Lily), is a species of daylily native to Asia. It is very widely grown as an ornamental plant in temperate climates for its showy flowers and ease of cultivation. It is not related to true lilies, but gets its name from the similarity of the flowers and from the fact that each flower lasts only one day.
The tubers, inflorescences, buds and flowers can all be cooked and eaten. Dried or fresh flowers are used in Chinese, Japanese, Korean, Thai, and Vietnamese cooking, and are known as golden needles.
