A small flowering plant (Anagallis arvensis) with bright red-orange flowers, often found in fields and gardens. The Japanese name literally means 'red-flowered glasswort chickweed'.

I found a scarlet pimpernel by the roadside.
Scarlet pimpernel is a naturalized plant originally from Europe.
ルリハコベ (Anagallis foemina) is a closely related species with blue flowers, while アカバナルリハコベ has red-orange flowers.
Katakana spelling is standard for this plant name; usually written in kana.
Kanji spelling is very rare and mainly encountered in botanical texts or dictionaries.
The name combines 赤花 (red flower), 瑠璃 (lapis lazuli, referring to the blue-flowered relative ルリハコベ), and 繁縷 (chickweed). The exact derivation is uncertain, but it likely describes the plant's appearance in contrast to the blue-flowered species.
