The question of circumstance...
What is a mutation?
A mutation, also called a ‘sport’ in English, or lusus in French, is a botanical phenomenon in which a part of a plant develops in a way that is totally different from the rest of the plant. This difference may concern :
- color: a variegated stem on ivy that is not variegated, for example
- on shape: clinging leaves on ivy with flat leaves, for example
These mutations are of natural origin. They are not the result of human intervention or hybridization. They may be the result of the plant’s adaptation or reaction to stress or changes in growing conditions.
Ivy is very familiar with this kind of phenomenon. That’s why new cultivars are constantly appearing.
The most interesting mutations are multiplied by cuttings. If the mutation is stable, it can lead to the creation of a new cultivar.
