Common Names

Dumb Cane, Dumbcane, Dumb Cane Plant, Tuftroot, Gold Dieffenbachia

Summary

Dieffenbachia seguine, commonly called the Dumb Cane, is a tropical evergreen houseplant native to Central and South America and Caribbean islands. It forms an erect, cane-like stem with large oval to oblong leaves green with patches or blotches of cream or white, creating a striking variegated display; indoors, plants are typically compact, up to about 1 meter tall.

It prefers bright indirect light, warm temperatures around 18–29°C, and high humidity, with soil kept evenly moist and the top inch drying between waterings in well-draining loamy or peat-based mixes. Propagation is possible by stem cuttings or air layering, and fertilization with a balanced liquid fertilizer every 4–6 weeks during the growing season supports growth. The sap is toxic if ingested, so gloves are recommended and pets and children should be kept away; the plant is valued as decorative indoor foliage and is noted for air-purifying properties, including removing formaldehyde, benzene, and trichloroethylene.
