A single flower stands alone, poking out of the sandy ground. A little distance away, there are leaves resembling small ginkgo leaves, overlapping and creeping over the sand. It must be a flower that has bloomed on a stem growing from those leaves. I took a picture and searched it on Google Lens, and it came up as Hamanigana (浜苦菜). It grows in sandy areas along the coast all over Japan, spreading with long underground stems. The leaves are thick with long stalks, and even if they get covered with sand, they soon extend their stems and bring the leaves back up to the surface. So, that’s probably why this flower is also blooming alone on the sand. The blooming season is from April to October, and the flower closely resembles that of a dandelion. Like dandelions, its seeds have fluffy hair, which helps them spread in the wind. The Chinese character ‘菜’ (meaning vegetable) suggests that the young leaves can be eaten in early spring. The taste is bitter, which is why it’s called ‘苦菜’ (bitter greens).
花だけがポツンと一つ砂地から顔を出して咲いています。少し離れた所にイチョウの葉を小さくした様な葉が重なり合って砂地を這っています。そこから伸びた茎に咲いた花なんでしょう。写真にとってGoogleレンズで検索したらハマニガナ(浜苦菜)とありました。日本全土の海岸の砂地に生え、地下茎を長くのばしてふえるそうです。葉は厚く、長い柄があって、砂をかぶっても、すぐに茎をのばして葉を砂の上にだすそうです。だから、この花も同じように砂の上にポツンと咲いたんでしょうね。花期は、4月から10月で、タンポポの花によく似ています。果実はタンポポと同様に綿毛が付き、風で広がります。漢字名の「菜」が示すように春先の若葉は食用にもなります。味が苦く「苦菜」になったんでしょうね。
