Katakana spelling is common for plant names and is the usual written form for this species.
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.
