Description

Dieffenbachia maculata is typically grown as a houseplant. It requires medium light levels and moderate indoor temperatures. This plant can be toxic for pets and children.

This plant has an exotic appeal and has wonderfully shaped leaves with brush strokes of cream, yellow and white which enhance the shape of the leaves. The rich color of green with its brush strokes of color allow this plant to stand out and shout out to be seen in your home.

Quick ID Hints:

  • Leaf is elliptic-oblong, blotched with cream
  • Main lateral veins number more than 8 (usually ca 20)
  • Stem is present on older specimens

Evergreen tropical perennial shrub to 8', erect and scarcely branched.

Desired in indoor settings for its erect habit and large, variegated leaves; blooms rarely in interiors. 

Distinguishable usually from Aglaonema species by counting obvious lateral veins- Aglaonemas usually have 5-8 main veins whereas Dieffenbachias have more than 8 (usually around 20-30). 

Distinquished from Spathiphyllum by presence of sugarcane-like stem. 

Nickname 'dumbcane' refers to the effect of the irritating sap (oxalate crystals) on the soft portions of mouth and throat acting like an acid; burning sensation causes gasping for air carrying crystals to larynx; scar tissue developing in larynx distorts sounds or makes talking difficult, causing one to become dumb, unable to speak. 

Always make sure to wash hands after handling plants; Keep hands away from eyes & mouth. Be alert for toddlers & house pets (e.g. cats) eating leaves. 

Used as specimen or background plant. 

Intolerant of low winter temperatures, cold drafts and overly wet soil; prefers medium to high light, dry soil and medium relative humidity; pest/disease problems.
