[Overview]
A perennial 7–20 cm tall, found in moist places such as inside and at the edges of mixed woodland, at the edges of Japanese cedar forests, and along roadsides.
It has a short, thick underground stem.
Many stems emerge; they are rough, with many white spreading hairs.
There are basal leaves and stem leaves.
The basal leaves are oblanceolate, 7–20 cm long and 2–5 cm wide, and appear in large numbers in a rosette.
The stem leaves are simple and alternate, smaller than the basal leaves, clasp the stem at the base, and become smaller toward the top of the stem.
The flowers are sparsely borne in a raceme at the stem tip.
The inflorescence does not branch.
The flowers are 1–1.5 cm across, pale bluish purple with a yellow center.
The corolla is 5-lobed.
After flowering, the flowers hang downward.
The fruit is a schizocarp (splitting into mericarps) with smooth margins and no hooked spines.
