ドクダミ
ドクダミが咲いています。独特の匂いがする多年生で、日陰でもよく育ちます。４枚の白い花弁をもつように見えますが、白い部分は総苞と呼ばれる花の集まりを包む葉が変化したものです。中央の黄色い部分が小さい花のあつまりで、１つ１つの花は花弁やがくをもたず、１本のめしべと３本のおしべからなります。
"Dokudami (ドクダミ)" plants are in bloom. They are perennial plants that have unique smell. They grow well even in the shade. They look like they have four white petals, but the white parts in the photo that look like petals are not petals. The white parts are called involucre, which are the leaves looking like flowers that wrap the flowers. The yellow part in the center actually consists of flowers. They are a pistil and three stamens and have no petals or sepals.
