シャガ
シャガが咲いています。人里に近い林に生える多年草で、もともとは中国から渡来したと言われています。花は一日花で、朝開いて夕方にはしぼみます。花は咲くものの種子はできないため、地下茎が伸びて広がるか、人によって運ばれて分布を広げていると考えられます。
"Shaga (シャガ)" plants are in bloom. They are perennial plants that grow in woods near human settlement. They are said to have originally come from China a long time ago. Their flowers are one day flowers that start to bloom in the morning and wither in the evening. As they don’t produce seeds though flowers bloom, it is assumed that the plants have spread by underground stems or humans.
