noun
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.
ヒヨドリバナは秋に白い小花を咲かせる。
Eupatorium makinoi produces small white flowers in autumn.
このあたりの山道にはヒヨドリバナがたくさん生えている。
A lot of Eupatorium makinoi grows along the mountain path around here.
フジバカマ (Eupatorium fortunei) is a related species often cultivated for its fragrant flowers, while ヒヨドリバナ is a wild species with less conspicuous scent.
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.
