- 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.
