Why Dieffenbachia Is Called Dumb Cane — and Why the Name Matters
Dieffenbachia's common name, dumb cane, comes from a genuine and documented effect of its sap: chewing the leaves or stem releases calcium oxalate crystals that cause painful swelling of the mouth and throat severe enough to temporarily impair speech, which is where the name originates. This makes it a genuinely more serious household hazard than most other popular foliage plants, particularly around small children and pets who are more likely to chew on leaves out of curiosity, yet it's frequently sold with no more warning than any ordinary decorative houseplant. The sap can also irritate skin on contact during pruning or repotting, so handling with gloves is a reasonable precaution rather than an overcautious one. Households with young children or pets that chew on plants are usually better served by a less risky foliage plant, or by keeping dieffenbachia well out of reach entirely.
