The Yucca makes a very easy house plant as it requires little maintenance yet gives good structure and provides a focal point. These striking house plants have good architectural presence and they are easy to care for. In fact, they can be grown either indoors or out. Yuccas have strappy, sword-shaped sharp foliage which maintains a good structure as it is stiff. The leaves grow from a woody stem and having multiple stems in one pot forms a great visual effect. The plant produces new leaves on the top of the stem and the older foliage yellows before falling off.
