Dieffenbachia Sterling is a stunning variety of Dieffenbachia with dark green leaves and a contrasting cream vein running down the center of each leaf. Dieffenbachia's common name, Dumb Cane, comes from the fact that the liquid that drips from its leaves can cause a temporary loss of speech if ingested. Due to its toxic juices, this plant is not recommended for homes with small children or pets that chew on your plants.
