I spotted this plant today during my evening walk about the yard.
I thought that even though this is a native plant, it looks alien. As in extraterrestrial.
I also spotted some Japanese knotweed (Fallopia japonica)along the edge of the woods. I wasted no time in pulling that nasty stuff up. Left unchecked, it will take over a place and choke out all the native plants. I hope I got it all, but I will be sure to monitor that spot closely throughout the rest of the growing season.
