What is Leontopodium japonicum

Leontopodium japonicum or Usuyukisou (scientific name: Leontopodium japonicum) is a hardy perennial in the family Asteraceae native to Japan and China. It is native to the low-mountain to subalpine zone in Hokkaido and Kyushu. It produces rosette leaves and upright flower stalks from the rhizome. What look like white flowers are bracts.
