Spider plants are one of nature's high oxygen producing house plants. They are easy keepers, don't require a lot of attention or water. You an put them in pretty much any type of light, from low to high, partially shaded for fully drenched in sun.
The more direct sun they receive, you'll need to water a bit more frequently.
Solid green or variegated (green with white in the middle) are both available.
Small plants will need to be re-potted, while the larger babies will come in a decorative pot, as they are already established, but if you want them to grow faster or fill out more, you can always re-pot into something larger.
