タチチチコグサ
セカンドオークヒルでタチチチコグサが咲いています。空き地などに生えるキク科の1年草または越年草です。チチコグサと名の付く北アメリカ原産の帰化植物の一種で、近年数を増やしているようです。
"Tachi-Chichikogusa" plants are in bloom in the Second Oak Hill. They are annual or winter annual plants in the Asteraceae family that commonly grow in vacant lots and other open areas. Native to North America, this naturalized species is one of several plants whose Japanese names include "Chichikogusa." It has become increasingly common in recent years.
