I had these in the Z5 garden, but they were too busy. I've gotten them mostly removed from here to next to the driveway or out in the pasture. I will have to stay on it, or they will keep coming back.
There's a bunch in the back section of the KK garden that I've been thinking about taking out as well. They need to at least be thinned.
They are starting to look nice next to the driveway.
