What is the geographical distribution of this plant?
This plant is native to the high-altitude alpine zones of the Japanese archipelago, specifically found on the islands of Honshu, Shikoku, and Kyushu. It typically inhabits subalpine meadows and rocky slopes where the soil remains moist and cool. These populations are often restricted to specific elevations ranging from mountain ridges to tundra-like environments. The distribution is closely tied to the presence of high-elevation ecosystems that experience significant seasonal snowmelt. Because of these specialized habitat requirements, the species is localized to certain mountainous regions rather than being widespread across the entire country.
How is this plant cultivated?
