Plants that are toxic to llamas and alpacas

I searched through one of my manuals on plant poisoning in animals and found that Photinias contain cyanide that can cause poisoning. Llamas and alpacas are ruminants, which makes them more susceptible to cyanide poisoning than other animals. So, I would suggest that you not plant any photinias near where your llamas and alpacas have access to the plant.
