Houseplants You Can't Kill by Overwatering

3. Selaginella

If you like variety, you might also look at the Selaginella plants. These cute, tiny herbs grow in many different regions, including tropical jungles and arid deserts. They are diverse both in size and how they grow. Because many of the species grow in tropical locales, they have adapted to wet environments. Even the desert varieties respond well to lots of water and are notoriously hard to kill. When you forget to water them, they simply ball up and go dormant. Once you water them, they miraculously revive themselves and begin growing again.
