Dracaena Marginata, often called the dragon tree, is a popular indoor plant originally from East Africa that is often used to adorn homes and offices. Easy to care for because of its low light and water needs, it features green, thin leaves with red and yellow strips along the edges; these grow from a thin cane that can reach heights of 15 feet (or 5 meters). The best way to grow dracaenas is to buy a small one from a nursery and plant it in a simple pot.
