I talked last time about the popular bamboo-looking plant, Dracaena Sanderiana. If you remember, it's a really easy houseplant. Another one that's super-easy to take care of, and needs pretty minimal light, is the Spider plant, or Chlorophytum comosum. It has long narrow leaves, about an inch or so wide at their widest and narrowing to pointy tips. The leaves grow up and droop out and over the sides of the pot.
Here's one of mine:
I have it as a hanging plant, because of a cool thing it does. Over time, the spider plant sends out "branches" that grow what looks like a miniature version of itself at the end of the branch - those hangy things towards the bottom of the photo above. You can then pluck these little plants off, put them in water and wait for them to grow some white roots. At that point, you can actually plant that part in a new pot with some soil, and grow a whole new plant!
It's a great way to share plants with your friends, as well as to populate your home with lots of greenery.
Another bonus to the spider plant? They've been proven (science!) to help clean the air and help with indoor air pollution.
