The naming of cultivated plants is controlled in order to provide a functional worldwide system. All taxonomic matters in plants fall under the purview of the International Union of Biological Sciences (IUBS). As cultivated plants, daylilies come under the broad umbrella of the International Society for Horticultural Science (ISHS), which is subsidiary to the IUBS. In 1955, the ISHS appointed the American Hemerocallis Society (AHS) as the International Cultivar Registration Authority (ICRA) for Hemerocallis.
