Yucca is a genus of more than 40 perennial plants, shrubs, and trees. A few are grown as houseplants, including Yucca gigantea (also known as Y. guatemalensis and Y. elephantipes) and the Yucca aloifolia. Yuccas are native to the American Southwest, Mexico, and the Caribbean—they are visually interesting, looking similar to agave or dragon plants. Some are fast-growing plants growing up to two feet per year, while others grow slowly, about 5 inches a year. All are extremely drought tolerant.
Most species of yucca will grow into room-devouring monsters, but this takes such a long time that you’ll get many years of use as a houseplant before it overwhelms your space. Most can also be grown outdoors, able to withstand cold snaps down to 10 degrees Fahrenheit—some varieties can even survive subzero temperatures. Plant them outdoors in the early spring. Pet owners should take caution if adding yucca plants to their homes—all parts of the plant are toxic to dogs and cats (as well as horses).
