Description
A bold aroid with thick stems and large oval leaves patterned with cream, yellow, or white. It is common indoors, but it deserves real respect because chewing it can be painful.
Care
- Light: Bright indirect to medium light. Too little light weakens variegation and growth.
- Water: Let the top 1-2 inches dry before watering; do not keep soggy.
- Soil & potting: Well-draining aroid/houseplant mix.
- Humidity & temperature: Average humidity works, but warmer and slightly humid rooms help.
- Feeding: Light feeding during active growth.
- Repotting / propagation: Can become cane-like and top-heavy with age.
Propagation
From stem/cane cuttings or by cutting and rooting the top. Each cane section needs a node. Keep warm, lightly moist, and clean. Wear gloves if sensitive to sap. See Propagation Basics.
Toxicity
Toxic to cats, dogs, and people. ASPCA lists Dieffenbachia as toxic; insoluble calcium oxalates can cause mouth pain, drooling, vomiting, and swelling if chewed.
