dieffenbachia

Dieffenbachia, commonly known as dumb cane, is a genus of tropical flowering plants in the arum family Araceae. Native to tropical regions of the Americas from Mexico to Argentina and the Caribbean, the genus comprises about 30 species. Dieffenbachia plants are evergreen perennials with upright cane-like stems and large, often variegated leaves. The leaves typically feature a central or irregular cream, yellow, or white pattern bordered by green.

In cultivation, Dieffenbachia is a popular ornamental plant, widely grown as a houseplant and occasionally outdoors in warm climates. It prefers bright, indirect light but tolerates lower light levels. It grows best in well-draining, rich soil and requires moderate watering, allowing the top edge to dry between waterings. It dislikes waterlogged soil and cold drafts; temperatures should stay above about 60–65°F (15–18°C). Fertilizing during the growing season supports production of new growth.

Propagation is commonly achieved by stem cuttings. Common pests include spider mites, mealybugs, and scale, while root rot can occur in poorly drained soil or with overwatering. Leaf tips may burn in very dry air or with excess fertilizer.

Toxicity: All parts of the plant contain insoluble calcium oxalate crystals; chewing or ingesting plant tissue can cause a burning sensation in the mouth and throat, swelling, and sometimes vomiting. Handling the sap may irritate the skin. Because of its toxicity, Dieffenbachia is typically kept out of reach of children and pets. The plant is primarily used as an ornamental indoors, valued for its varied leaf patterns and evergreen habit.
