Dieffenbachia does well in a semi-sunny to a shady location and does not need much sunlight.

The plant will, however, thrive in bright light conditions.

Bright light does make the ordinarily dark lush growth and color; the Dieffenbachia is known for to become dull.

Dieffenbachia can grow outdoors with lots of sunlight but needs protection from wind and the hot noon sun of summer or plants begin to look sickly.

Too much sun will burn the leaves, but too much shade on the heavy white/yellow varieties will cause them to be poorly colored.
