Spider Plant (Chlorophytum comosum)

Your grandmother had one. Her grandmother had one. Spider plants have been surviving in homes since the Victorian era. They produce baby "spiderettes" on long arching stems that you can snip and root in water or soil — free plants forever. They handle low light, inconsistent watering, and root-bound pots without complaint. NASA's Clean Air Study ranked them among the top air-purifying plants.
