It depends on where in the U.S. you are. In most areas that get little or no frost in the winter, it can stay outdoors all year, though it suffers in very hot, humid summers. It is most at home west of the Coast Ranges in southern California, where it is often used as a landscape plant. In colder climates, it is often used as an indoor-outdoor plant, or a straight houseplant--with ample light while indoors. It likes morning sun, fast-draining soil, infrequent but thorough watering, and very light feeding.
