Gina1960 said: The variegation in Monstera deliciosa albo-variegata isn't a from a 'disease'. The variegation is chimeric and arises from a genetic mutation that causes a loss of chlorophyll production in one or more cell tissue layers in the meristem tissue. That translates out through the leave as variegation.
Unlike Monstera deliciosa Thai Constellation, which is considered a 'stable' variegation pattern, albo-variegata is extremely UNstable and can result in reversion to either a completely green plant or a total reversion to a completely white plant, the difference being the totally green plant will survive, and the totally white one will not.
