フィールド日記

 校舎の周りでツワブキが咲いています。キク科に典型的な頭状花で、中心の両性の筒状花とその周りの雌性の舌状花からなります。本来は海岸近くに自生しているようですが、古くから栽培されており、庭など身近なところでよく見られます。

"Tsuwabuki (ツワブキ)" plants are in bloom around the school building. They have a typical flower head of the asteraceae family ,which consist of bisexual tubular flowers in the center surrounded with female ligulate flowers. "Tsuwabuki (ツワブキ)" flowers originally grow near coasts, but they have been cultivated for a long time, so you can see them in familiar places like yards and gardens.
