Hemerocallis fulva, the Orange Daylily, 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. It is an herbaceous perennial plant growing from tuberous roots, with stems 40–150 cm tall. The leaves are linear, 50–90 cm long and 1–2.8 cm broad. The flowers are 5–12 cm across, orange-red, with a pale central line; they are produced from early summer to late autumn on spikes of 10–20, with the individual flowers opening successively, each one only lasting one day.
