Is Corn Plant (Dracaena) Toxic to Iguanas?

Is Corn Plant (Dracaena) Toxic to Iguanas?

Your iguana climbs your corn plant (Dracaena fragrans 'Massangeana'). While reptile toxicity data is limited, caution is strongly advised.

Known Mammal Toxicity

ASPCA lists corn plant as toxic to cats and dogs, causing:

• Vomiting, depression, appetite loss
• Drooling, incoordination, weakness
• Dilated pupils, breathing difficulty, abdominal pain, increased heart rate (cats)

Reptile Risk Assessment

• No specific iguana studies exist.
• Many plant toxins affect reptiles similarly to mammals.
• Iguanas are folivores—they will eat accessible foliage.

Recommendation

Remove the plant or restrict iguana access completely. Provide safe browse: hibiscus, mulberry, dandelion greens, or commercial iguana diets. The risk outweighs the climbing enrichment.
