This is an excerpt from an article I found online explaining how they can be dangerous to reptiles.
"Reptiles are becoming increasingly popular as pets, and they too are affected by a number of toxic plants. Azaleas and Oleanders can be dangerous if eaten by your lizard or turtle. Buttercups and Jimson Weed will affect your reptile's nervous system, while Flax and Soybean plants contain dangerous levels of toxic nitrates. Reptiles require veterinarians that specialize in their care, and if your reptile ingests something that you believe to be toxic you should contact your veterinarian immediately."
