Eupatorium makinoi; a species of boneset
A perennial plant in the Asteraceae family, native to East Asia. The name is sometimes used broadly for similar Eupatorium species.
Eupatorium makinoi produces small white flowers in autumn.
A lot of Eupatorium makinoi grows along the mountain path around here.
Kanji form is rare and mainly encountered in botanical or literary contexts.
The name ヒヨドリバナ likely derives from the bird ヒヨドリ (brown-eared bulbul) and 花 (flower), possibly because the plant blooms around the time when bulbuls are active, though the exact origin is uncertain.
