Dieffenbachia is one of the easiest indoor houseplants to grow -- and one of the most common indoor plants. This tropical shrub shows off lush leaves that are usually marked in shades of cream, yellow, or white, making dieffenbachia a top pick for brightening dim corners indoors. A shorter, more compact variety, 'Tropic Snow' shows off creamy-white leaves flushed with green and edged in rich, dark green. Dieffenbachia plants like regular watering, but they don't ever want the soil to be wet or soggy for extended periods. Because more indoor plants die from over watering than under watering every year, it's best to keep dieffenbachia on the dry side if you're in doubt about whether to water it. Just like most tropical houseplants, grow dieffenbachia in a relatively warm, humid spot with plenty of light. That said, dieffenbachia will tolerate low-light spots, as well. If the leaves develop brown tips or edges, the air may be too dry. Dieffenbachia is generally known as Dumb Cane, Exotica or Tropic Snow and it's poisonous to both dogs and cats.
