Hemerocallis is important economically as medicinal, poisonous, edible, and/or horticultural plants, which have been in Chinese culture for thousands of years (W. Erhardt 1992). Hemerocallin, a root neurotoxin, can be both poisonous and useful medicinally as an analgesic, diuretic, arsenic-poisoning antidote, and treatment for schistosomiasis (J. A. Duke and E. S. Ayensu 1985; W. Erhardt 1992; Hu S. Y. 1968). In Asia, flowers (buds and perianths), shoots, and tuberous roots (following suitable preparation) are important foods (G. Kunkel 1984). Daylilies are among the most popular North American garden plants. Registered cultivars of Hemerocallis now exceed 38,000, including more than 13,000 named clones of H. fulva (G. Grosvenor 1999; R. M. Kitchingman 1985; R. W. Munson Jr. 1989; W. B. Zomlefer 1998).
Hemerocallis has been included in a broadly circumscribed segregate family Hemerocallidaceae with 13–18 genera mainly from the Southern Hemisphere, especially Australia (W. B. Zomlefer 1998; H. T. Clifford et al. 1998), or placed alone in a monotypic Hemerocallidaceae (A. L. Takhtajan 1997).
The dwarf, yellow-flowered Hemerocallis minor P. Miller, grass-leaf daylily, has been reported as a local escape in Oregon.
