Hemerocallis fulva, the Orange Daylily, Tawny Daylily, Tiger Daylily or Ditch 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.
