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. Dieffenbachia adds fun color and texture without flowers. Because it grows upright, it's an excellent choice to grow along an empty wall or near a large piece of furniture. It adds flair and drama to bedrooms, dens, offices, and other rooms.
