Artemisia argyi, herbaceous perennial about one metre tall, with short branches and a creeping rhizome （爬行的根茎；根部应该很发达，应该是一揪，一串根就起来了；今天还没有来得及去拔出来看）. Known as silvery wormwood or Chinese mugwort. 这个是中国的艾草， 或称艾蒿。It is native to China, Korea, Mongolia, Japan, and the Russian Far East. 可以用来做青团. 注意看图中标记的叶子是从叶茎同一个位置长出来的。 最顶端的叶片是完美对称的。非顶端的叶片不是。 另外注意看叶片的锯齿形状。背面有几乎看不见的白毛，所以比正面看起来有点偏白。https://en.wikipedia.org/wiki/Artemisia_argyi

去前院种东西，先除杂草，发现去年除的杂草又长出来了。拔了一棵，正要扔，突然觉得这个有点像前些日子和家人念叨的艾草（老父亲风湿关节炎；有朋友说艾灸有用；老父亲试后认同）。问了一下朋友，都说像。有人建议用识图软件识别一下。结果给出三个答案。挨个看了一下，结论是：对的。我院子里那生命旺盛屡除不尽的正是艾草。简直立刻有捡到宝的感觉。

顺便说说另外俩个在美国没有见到的这个大家族成员：
Artemisia carvifolia，中文名叫青蒿，背面绿色，无毛，但是不含“青蒿素”。https://baike.baidu.com/item/%E9%9D%92%E8%92%BF/603320
Artemisia annua，中文名叫黄花蒿，花有点黄绿色。无毛。叶茎有点棕色。含“青蒿素“。 屠呦呦就是因为提炼到这个东东，并证明对治疗疟疾有效而获得的诺奬。
