What's the name of the picture of Setaria viridis?

It's nice to take the names of two tails in the photo of Setaria viridis. Dog tail grass can be called double tail. Because it is more like two eyebrows, it can also be named Mel. Setaria viridis is probably one of the most widely distributed flowers in China, with too many childhood interests and fantasies behind it. I believe that 80% of people have made cute animals out of green bristlegrass in their childhood, and also made a harbor of hearts in their childhood.
