Plant Cuttings

I don't know its name, but this is the best houseplant. Put it in a vase with water for some slow-growing no-maintenance greenery, or plant it in soil and it'll grow into a long vine in no time. Doesn't need much sun, and is pretty forgiving if you forget to water it for a few weeks. Once the cuttings have established themselves you can snip off a piece and stick it in water to propagate another plant.
