The daylilies of Oze National Park are characterized by their dark orange-yellow petals, of which it has six. The best time to see the daylilies at Oze National Park is from late June to August, as they grow at high elevations in the mountains, where temperatures can vary greatly.

In Japanese, the daylilies at Oze National Park are called Nikkokisuge (ニッコウキスゲ, 'Nikko Daylilies'), which comes from the fact that there are many colonies of them that can be found growing in Nikko, Tochigi. Other than Oe Marsh, these daylilies can be found at Senjogahara Marshland and in the Kirifuri Highlands of Nikko, Tochigi, where the name originated, as well as in Nagano Prefecture, which is home to the Kirigamine Highlands and Kurumayama Highlands, where the flowers can be found growing in colonies.

What makes the flowers so special is the vivid color of their petals. The flower is known to bloom in the morning and close in the evening, and it's almost as if it puts all of its energy into blooming to show you its brilliant beauty.
