What is Aruncus aethusifolius

Tanna Chidakesashi (Aruncus aethusifolius)

Tanna Chidakesashi (Japanese name: 丹那乳茸刺, scientific name: Aruncus aethusifolius) is a dwarf perennial herbaceous plant of the family Saxifragaceae, genus Aruncus, native to the Korean Peninsula.
In Japan, it grows wild from the Kinki region westward, including Shikoku and Kyushu, in sunny forests, along mountain valleys, and on rocky areas.

The stems are 10–20 cm tall.
The leaves are 2–4 times odd-pinnate compound, with leaflets that are ovate or obovate, about 3 cm long, and have serrated margins.
From June to August, it produces racemes bearing many white or pink flowers with a diameter of 0.3–0.5 cm.
Due to its short height, it is often used as a potted plant.

Origin of the Name
In the Japanese name “丹那乳茸刺” (Tanna Chidakesashi), “丹那” (Tanna) is an old name for Jeju Island, its place of origin, and “乳茸刺” (Chidakesashi) refers to the custom of threading edible Chidake mushrooms (Lactarius volemus) onto its hard, slender stems to carry them home.
