It is a wildflower that grows wild on rocky terrain in the mountains of the Kanto to Chubu regions of Honshu.The grass is 30-70 cm tall and has thick rhizomes but thin stems and leaves. The rhizomatous leaves are nutritive, ovate, and alternate. The leaves attached to the stem are narrowly lanceolate to broadly linear, 7-15 cm long, and have serrated edges.

The genus name "Adenophora" is a reference to the genus Adenophora , and the species name "takedae" is a dedication to Hisakichi Takeda, a Japanese alpine plant researcher. The Japanese name "Iwasyazin" is derived from its resemblance to Korean ginseng, which grows in rocky areas, has the same bell-shaped flowers, and produces a herbal drug called shajin from its roots.

The flower is similar to that of the ginseng (scientific name: :Adenophora triphylla var. japonica), but the flower can be distinguished from the ginseng by the fact that the flower stalk does not protrude from the corolla.
