Hemerocallis minor, commonly known as dwarf daylily, grassleaf lily or small daylily, is a plant in the family Asphodelaceae, native to Siberia, Mongolia, China and Korea. Despite their common name, daylilies are not true lilies (plants of the genus Lilium, family Liliaceae). Although the flowers of Hemerocallis and Lilium species have a similar shape, their growth habits, stems and leaf shapes are distinctive. The genus name Hemerocallis derives from the Ancient Greek hemera (‘day’) and kallos (‘beauty’), reflecting that the flower typically blooms for only one day, usually opening around sunrise.
