What is Diaspananthus uniflorus
kusa-yatsude (scientific name: Diaspananthus uniflorus) is a perennial herb of the genus Kusayatsude in the Asteraceae family, endemic to Japan. It grows wild in the forests of Honshu, Shikoku and Kyushu. The leaves are palmately lobed with five to seven lobes, and the lobes have two to three shallow lobes. In autumn, the long conical inflorescences grow downward to produce slender, tubular bracts and a single dark purple head flower within. The apex of the flower tube is fully lobed and recurved.
It is an herbaceous plant, and its name comes from the fact that its leaves resemble those of the lamprey.
