Lithops

If your plants are less sore from lack of light causes in addition to absent or too busy to devote sufficient attention, the living stones (Lithops) plant for you. Unusual in the form these small plants have two leaves instead of juicy fat produced every spring, a large flower in the fall. While these small plants four hours direct sunlight a day, they would do well to require light watering only twice a year: in spring after new leaves have the old (but not absorbed during the transition) and fall when the flowers appear.
