If you appreciate beautiful, variegated foliage, then Dieffenbachia Plants are perfect for you. Large, oval-shaped leaves flutter atop their upright stems, resulting in striking movement that will add botanical interest to any environment. While Dieffenbachia plants have received their fair share of undeserved fear, they make great indoor plants. But please be aware that they are poisonous, so keep out of reach from pets and children.
