on leaves of 'Buckeye Boysenberry'
Variegation occurs in several distinct patterns. Edge variegation results in color differences along the margins of the leaves, while the midribs remain green. This is often called Tommie-Lou variegation, after the hybridizer Tommie Louise Oden. In crown variegation, the variegated color is limited to the leaves in the center, or crown, of the plant and is lost as leaves mature and grow outward. Ethyl Champion developed many varieties with this type of variegation, and her name is often associated with it. Mosaic variegation produces tiny streaks and splashes of color throughout the entire surface of the leaf.

If you have a “variegated” variety that looks entirely green to you, don't worry. Variegation tends to be variable. Sometimes variegation will be lost when a plant is propagated, but more often it is temporarily gone due to some environmental condition. Many of my variegated plants grow out green during the warmer summer months. During cooler winter conditions, their striking colors return. Too much light or too much fertilizer may also “green up” a variegated plant. If your plant once had variegated leaves, odds are good that it will have them again.
When propagating a variegated African violet, choose a leaf cutting that has as much green as possible. The developing plantlets need the green chlorophyll in the mother leaf to provide energy. Sometimes plantlets will form that are entirely white or pink, without any green. If you separate these from the mother leaf, they probably won’t survive. A little weak fertilizer or fish emulsion may green them up.

African violets with a lot of variegation need less light and are more likely to be burned by too-bright light. They’d rather be a little further from the window than their deep green siblings. If you're growing under fluorescent lights, the cooler ends of the fluorescent tubes are ideal locations for highly variegated plants.
You can find named cultivars of African violets with specific types of variegation and other characteristics by doing an advanced search through African violet entries in PlantFiles.

Where can you get these plants? Although variegated African violets are sometimes sold at local nurseries or “big box” stores, mail order vendors may be better sources. Many of the excellent companies mentioned in the African violet care and related links “sticky” thread near the top of the African Violets and Gesneriads forum (subscribers only) are also rated in the Garden Watchdog. Trading leaves and plantlets with other forum enthusiasts is also an excellent way to try new varieties.
I love variegated African violet plants, whether or not they are in bloom. With flowers, a variegated African violet is stunning. Without a single bud, it's still beautiful. Variegated varieties are less common but well worth searching out. Pick up an African violet or two with such lovely leaves, and soon you’ll be viewing blooms as a bonus!
