Reversion is when a plant known for a particular leaf shape, variegation, colour, or other striking characteristic ‘reverts’ back to a different form often found in the plant’s parentage. The term is often used to describe a variegated shrub or tree that produces non-variegated shoots.
Eventually if left, this original form of growth, which is usually more vigorous, will take over the plant. Reversion can have several causes, like genetic mutations, Chemically induced hormonal change whether by insect damage, bacteria, fungus, spraying, or viruses.
Often these reversion shoots called sports can create new varieties of plants that can be propagated by cuttings to provide new varieties.
This is mainly a problem with variegated trees and shrubs, with plants starting to grow pure green leaves. However, the mutations within these plants are not always stable and can be prone to ‘reverting’ back to the original parent.


Control

Shoots that have reverted are usually much more vigorous than the variegated plant and should be pruned out completely or cut back into wood containing the wanted foliage.
