Dieffenbachia

Dieffenbachias​ feature pointed, ovate leaves in a variety of combinations of green, cream, and white colors. A large, well-grown dieffenbachia can reach 10 feet, with leaves 20 inches long. However, the plants will rarely reach this size in typical indoor conditions, where 3 to 5 feet is more common. Dieffenbachia is a fast-growing plant that can achieve 2 feet in height within a year of planting a rooted cutting, provided it gets enough light. Though the name "dumb cane" has fallen out of favor as a derogatory term, it was called that because the plant is highly toxic to humans, dogs, and cats.
