Obedient Fence

Let me explain the title:

Physostegia virginiana is commonly known as Obedient Plant or False Dragonhead. Thats the flower in this photo Its obedient for a reason, the flowers on this plant, one little flower at a time, will stay where you move it, if you just even touch it and move it it will stay obedient in that spot and grow like that. Just don't move them too hard or they snap off but its quite a fun plant

And this is part of the fence in the park.
