The Dieffenbachia are tropical members of the Araceae family and important indoor ornamental plants because of their attractive variegated leaves. The Dieffenbachia inflorescence consists of an upright spadix surrounded by a spathe. Staminate flowers are attached to the top of the spadix while pistillate flowers are attached to the lower portion. Treated plants flowered uniformly with a significant increase in the number of blooms per plant. Plants flowered heavily after a single foliar spray of 250 to 1000 ppm. Plants have since been induced to bloom during different seasons of the year.
