ヒメジソ
ススキ野原でヒメジソが咲いていました。湿った陽地などに生えるシソ科の一年草です。近縁種のイヌコウジュと似ていますが、毛の量や生え方などに違いがあります。ススキ野原ではどちらも見ることができます。

"Himejiso" plants are in bloom in the Japanese pampas grass field. They are annual plants in the Lamiaceae family that are typically found in wet, sunny places. They closely resemble a related species called "Inukouju", but the two can be distinguished by the amount and growth pattern of the hairs on their stems and leaves. Both species can be found in this field.
