Natural, Chimeral and Viral Variegation (Splash) in Plumeria

Variegation in plants is described as the appearance of differently colored zones in the plant's organs such as leaves or flowers, and it is mostly manifested as stripes, blotches, steaks or splashes. The word "Splash" has been widely used to describe pigmentation patternings or variegations in plumerias by a number of plumeria glowers. Splash such as natural splash is a form of natural colorations which is genetically regulated but its phenotype can be affected by a number of factors, and is often mistaken for other kinds of splashes or vice versa. Differentiating between virus induced symptom (viral splash), natural coloration (natural splash) and variegated mosaics due to shoot apical meristem layer-specific mutations (chimeral splash) in plumeria can be challenging. This requires experience, and many times it needs to be investigated scientifically in laboratory. Below is a brief overview on basic characteristics of these splashes and a few similar variegation
