Do All Orchid Species Have Alba (White) Forms?

A reader asks whether most orchids have an "alba" (white/pigment-lacking) version rather than other colors.

Expert Perspective

While sweeping generalizations are risky, experience suggests virtually all orchid species do have alba forms. These are usually rare natural mutations. Because collectors find them attractive, alba forms are often artificially propagated (via mericlone or division) and become far more common in horticulture than in the wild.

Alba forms lack the typical pigments (anthocyanins, carotenoids) due to a genetic mutation blocking pigment synthesis. They are not a separate species—just a color variant.
