Hidakaso
An Endemic Alpine Plant Found Around Mt. Apoi
An endemic alpine plant that grows only in a limited area around Mt. Apoi in the Hidaka region.
Hidakaso is an alpine plant that grows in peridotite scree near the 810-meter summit of Mt. Apoi. Peridotite is a distinctive type of rock originating in the Earth's mantle that has been exposed at the surface, occurring only in limited areas of the southern Hidaka Mountains. After the spring snowmelt, white flowers about 2 centimeters in diameter bloom at the tips of stems 10 to 25 centimeters tall.
Adapted to this distinctive geological environment, the plant was formerly called “Tsushimaso” after its discoverer. It was later given the name “Hidakaso” as an alpine plant representing the Hidaka region. Today, it remains an endemic species that grows only in limited environments around Mt. Apoi.
In recent years, shrinking populations due to global warming and environmental changes have become a concern, leading to conservation and protection efforts. Hidakaso offers an opportunity to learn about Mt. Apoi's distinctive geological environment and the plants adapted to it, as well as the relationship between the local environment and plant growth.
