Foliage plants with variegated leaves require brighter light, because their two-toned leaves have less chlorophyll, which is needed for growth. If the plant is not getting enough light, it will respond by making all-green leaves so it can make more chlorophyll.

Can you force variegation in plants?

Variegation is not easily induced and can't be done so at home. Best to get a cutting of a variegated plant from a friend or pass your's on in order to keep the variegated plant love flowing.

Does light increase variegation?
