Crystal, all parts of the Yucca species?including Y. elephantipes (yucca cane)?are indeed considered to be toxic. However, the concentration of toxins can vary from one part of a plant to another, depending on soil conditions and other environmental factors. As our website indicates, Yucca spp. has the potential to produce gastrointestinal irritation, including drooling, vomiting and diarrhea. It can also cause depression and, in severe cases, seizures.
