The Cordyline Plant typically has leathery leaves shaped like a spear with a variety of colors including green, red, yellow, white, purple, and purplish-red. Caring for these plants indoors is simple and straightforward, but they must be kept warm and they need a lot of light.  It is important to keep the soil continuously moist. Reduce watering during the winter and water your plant whenever the soil surface starts to feel dry.
