Zamioculcas zamiifolia (ZZ) plants are popular houseplants because they are attractive, easy to care for, and they grow well in all lighting conditions. We have ZZ plants growing outdoors and indoors, and we love their green, shiny leaves. However, we recently discovered one of our ZZ houseplants producing a stem with leaves having lesser chlorophyll than the norm. The leaves are mostly white in colour and our ZZ looks like a variegated plant.
I guess the ZZ plant does not grow well in all lighting conditions after all. Chlorophyll, the green pigment found in plants, is needed for them to absorbs incoming light to photosynthesize. Photosynthesis actively uses sunlight to produce energy for plants.
Green plants with little chlorophyll indicate the need for more sunlight; such plants should be moved closer to a sunny location. Lack of sunlight will stunt a plant’s growth and may eventually cause its death.
