Dieffenbachia seguine

Dieffenbachia spp. or Dumb Cane are plants belonging to the family Araceae, characterized by large green leaves heavily mottled with yellow, white or light green.

The exuberant foliage gives an air of jungle to your home.

Many varieties are available in the trade, from dwarf varieties to plants that can measure over a meter high.

Caution! The plant contains calcium oxalate and is toxic. Though rarely lethal, it irritates the skin or provokes swelling of mouth and throat when ingested, which can prevent you from speaking, hence the name Dumb Cane.
