What is variegation?

Typically variegation occurs in a combination of two or three shades: white, cream or yellow, and every now and again more vibrant colours like red or pink. In the wild it might occur because of a mutation in plant cells that affects the production of chlorophyll (what makes plants green and allows them to photosynthesise or make energy). These mutations are called sports, breaks or chimeras in ‘horti’ talk. More rarely, variegation can also be the result of viruses like the tobacco mosaic virus which causes regular ‘mosaic’-like patterns on the leaves and stems of plants. Where Plant Breeders find these mutations of a pure green plant attractive, they are able to vegetatively propagate (by cuttings, grafting or division, but not by seed) more plants with the same effect.

If you find that your plant is losing its variegation and you see plain green leaves appearing, this is called ‘reversion’ and it means your plant is trying to return to its original form. Just cut these bits out. 

Because variegated plants have less of the green chlorophyll required to photosynthesise and grow, they need more light for their green bits. Pop them in a sunny spot or at least somewhere they get sun for some of the day. The more sun they get, the more variegated those leaves will look. 

Variegation adds colour, pattern, movement and playfulness to your plant collection. It also gives you different tones to pick up in your decor - bonus. Bear in mind that the more variegation you introduce, the busier your collection will look. It’s best used sparingly to break up otherwise monotone shades of green. 

The other benefit of plants with white, light green or yellow stripes or patches is that they can be used to brighten and liven up shadier corners.
