A perennial plant of the lily family (APG classification: Xanthomoniaceae). Native to China, it is a variant of the nocturnal Hemerocallis nigricans and Hemerocallis nigricans, but unlike Hemerocallis nigricans, it blooms nocturnally and in the daytime, producing bright yellow flowers. The inflorescence reaches 20 cm in length and is highly branched. The flower tube is 2-3 cm long, and the perianth pieces are 6-8 cm long. It grows in colonies in the somewhat dry grasslands of the coastal sand dunes of eastern and southern Hokkaido.
