Question: 1 / 400

What is the common name for Dieffenbachia?

Dumb Cane

Dieffenbachia is commonly known as Dumb Cane. This name originates from the plant's toxic properties, which can cause temporary speechlessness if its sap comes into contact with the mouth or throat. The plant contains calcium oxalate crystals, which can irritate the tissues, hence the nickname.

In contrast, the other options represent different plants with distinct characteristics. The Peace Lily is known for its glossy leaves and white flowers, Pothos is a popular trailing vine with heart-shaped leaves, and the Spider Plant is recognized for its arching leaves and the small plantlets that appear on long stems. Each of these plants has its own unique care requirements and features that set them apart from Dieffenbachia. Understanding these differences enhances knowledge of plant identification and care in the world of floriculture.
