Larkspur, especially tall larkspur, is a significant cause of cattle poisoning on rangelands in the western United States.Larkspur is more common in high-elevation areas, and many ranchers delay moving cattle onto such ranges until late summer when the toxicity of the plants is reduced.arkspur, especially tall larkspur, is a significant cause of cattle poisoning on rangelands in the western United States.
