Spider plants are perhaps the most well known plant in the world. Most people recognize them, have owned them, or have grown them at some point in time. These are great plants for those who are just starting out with plants as they are very tolerant of neglect. Many people enjoy spider plants because every type has been shown to remove the toxins out of the air, making the air better for breathing. There are seven different types of spider plants but generally they all look very similar. They are usually either plain green, or green with white margins, or green with a central white stripe. The untrained eye can often not discern one type of spider plant from another.
