Is it legal to plant stinging nettles in Utah? I checked noxious weeds lists for utah but it only shows what's already here. This is a plant that I'm very interested in growing, but I don't want to be hit with a fine for it. A bit more info: The plans of growing it are in a container while cutting off all flowers (this is a plant that I don't want growing out of control, for obvious reasons.)

Just to make sure I get a 100% correct answer I would like references if possible.
