Always protect dieffenbachias from cold and major changes in temperature. As these plants mature, lower leaves naturally drop to reveal attractive, trunklike stems. If the stems become too long and bare, you can rejuvenate the plant simply by cutting the stems back to about 6 inches tall. The plant will regrow below the cut. If repotting is necessary, do so in early spring.
Propagation is by cane cuttings, stem tip cuttings or air layering done in spring or early summer.
Camille' is one of the best-known dieffenbachia cultivars. It has creamy yellow leaves bordered in rich green. Its full growth habit gives it a lush appearance. Compacta' is more compact-growing than other varieties. Its cream colored leaves are brightly mottled with green, and it has a very full growth habit.
