フィールド日記

 ススキ野原でサワヒヨドリが咲いています。湿った明るい草地に生える多年草です。ヒヨドリバナに対して湿った環境に生育するためサワヒヨドリと呼ばれるようですが、ススキ野原では両種が混生しています。本校のススキ野原では、ヒヨドリバナに対してサワヒヨドリの花は赤みを帯びていて、花期も若干早いようです。


"Sawahiyodori(サワヒヨドリ)" plants are in bloom in the Japanese grass field. They are perennial plants living in sunny moist grass fields. "Sawa" in its name means "swamp". It is because they prefer moist places compared to "Hiyodoribana(ヒヨドリバナ)" plants, which is similar species to this one. You can see both "Sawahiyodori" plants and "Hiyodoribana" plants in the Japanese grass field. "Sawahiyodori" plants bloom a little earlier than "Hiyodoribana" plants and their flowers are reddish.
