What makes Warneckii a popular interior houseplant is not only due to its beautiful leaves but also because it can be grown in the form of a cane or in the form of a bush. Place them indoors in a place where they can get an indirect bright light.The Warneckii requires less water than most indoor plants. When watering, water lightly and slowly from above with purified water, allowing water to soak through to the roots, then tip out any excess water.
