The Polyscias Hawaiiana Ming, also called Arialia, is a unique air-purifying plant. This Polyscias is characterised by its soft, curly light-green leaves. Place the plant in a semi-shaded spot with a little sunlight now and then. The potting soil may always be moist, but make sure that you do not overwater the roots. This can cause root rot. We also recommend watering the leaves regularly.
