Misc FactsLike all Dieffenbachia, they are not a plant for homes with curious pets and small children because of the toxic leaves. These plants contain needle-like crystals of calcium oxalate that penetrate and irritate the mouth and throat tissues. Chemicals in the sap can also cause inflammation of mucous membranes. Plants in this family include dieffenbachia, philodendron, caladium, and elephant's ear. Symptoms of poisoning from dieffenbachia are intense burning and irritation of the mouth, tongue, and lips. Although rare, the swelling can seal off the breathing passages if the reaction is severe enough. Philodendron, Caladium, and Elephant's Ear produce the same symptoms when ingested. If a piece of the corm (underground stem) is eaten, symptoms are burning of the mouth and throat. Jack-in-the-pulpit is a native member to watch in this family. (www.plantkingdom.com)
