Note	Some authors have described that Hemerocallis fulva L. var. sempervirens (Araki) M. Hotta is a synonym of Hemerocallis fulva L. (var. fulva). However, I think Hemerocallis fulva var. sempervirens may be a dwarf variety of Hemerocallis fulva L. (var. fulva) at least, bacause Hemerocallis fulva var. sempervirens is relatively smaller than ordinary Hemerocallis fulva L. (var. fulva).
	Photos below are thoese of plants which have been identified as Hemerocallis fulva var. sempervirens by the Ohsaka City University Botanical Garden, and have been cultivated in a non-public back yard of the Ohsaka City University Botanical Garden. I took these photos after receiving special permissions. The plants were ca. 60 cm tall (including scapes), leaves ca. 10mm wide and flowers ca. 10cm across.
