@FerfeLaBat Did they use pictures from my wife's wildflower patch? I NEED RESTITUTION!
We knew they were invasive, and truth told, 3 years in - we are not getting the flowers over native weed ratio we hoped for.
Native weeds win.
So cat owners: if your cat loves these plastic springs but they keep getting lost under the couch...
Wrap the spring around something larger.
Boil some water.
Dip the spring into the water for less than a second.
It will now keep the shape you set it in.
