Hemerocallis fulva: flower

[Photo: Hemerocallis]Hemerocallis fulva, known in English as orange daylily or tawny daylily and in French as héméocalle fauve or lis d'un jour fauve, is a perennial native to Asia with showy orange lily-like blossoms. Daylilies are not true lilies; true lilies have shorter leaves than daylilies in whorls around the stem whereas daylilies have longer leaves all springing from the ground. Each flower of a daylily lasts only a day, hence the name. According to Invasive Exotic Species Ranking for Ontario (PDF), Hemerocallis fulva is a Category 4 Invasive (do not pose a serious threat to natural areas unless directly competing with more desirable vegetation). Still, I wouldn't recommend it, especially for Torontonians lucky enough to live near wild spaces. A native alternative is Canada lily (Lilium canadense).
