ユウゲショウ
ユウゲショウが咲いています。アカバナ科の多年草で、アメリカ大陸原産の帰化植物です。人里周辺で広く見られます。和名は夕方に開花することに由来するといわれますが、実際には日中から咲いています。

"Yuugeshou" plants are in bloom. They are perennial plants in the Onagraceae that originally come from the Americas. They commonly grow near human dwellings. Their Japanese name comes from the fact that they are said to bloom in the evening, but actually, their flowers are often already open in the morning.
