Perhaps not as exciting as the mythological chimera (a mishmash of snake, lion, and goat) chimeras in the plant kingdom refer to distinct types of plant cells within the same plant that have different characteristics. So in the case of African violets, you can end up with the beautiful pinwheel effect displayed here by the miniature variety ‘Petunia.’
These are no harder to grow than other African violets, though you may have to go to a specialty grower to find them. They also will not reproduce by leaf cuttings so you’re out of luck there unless you can get hold of a sucker(young plantlet that forms at the base of the mother plant. Petunia happens to form multiple crowns so could be easily propagated. It also has an attractive semi trailing habit. This plant is growing on a tiny plastic two inch pot that we dropped into this decorative cache pot for display.
