Types of Houseplants

Dieffenbachia
Dieffenbachia, Dumb cane

Dieffenbachia is one of the most spectacular houseplants and is grown for its large, variegated, leafy foliage. There are several popular varieties whose leaves vary in degree of variegation and color. They are hardy and withstand the indoors well. Their leaves and stems are poisonous.

Care

Plant in regular potting soil and allow the soil to dry between waterings. Best in bright, indirect sunlight, warm temperatures and low humidity.

Special Requirements

Although dieffenbachia tolerates lower light conditions, it grows best in brighter light. It is often overwatered causing the roots and base of the canes to rot quickly. When the lower leaves turn yellow, remove them. If the stem becomes bare and objectionable the top can be cut off and rooted in sand or water, the air layering method works, too. Caution: Dieffenbachia sap is toxic to open cuts. Be careful when removing the leaves or cutting the canes.
