Also known as Air Plants, Tillandsias are some of the oddest houseplants around. They are epiphytes, which means they absorb nutrients and moisture from the air, rather than soil. Instead of planting it in a pot, you can mount it on just about any surface; instead of watering it, you just need to give it a generous misting with a spray bottle a couple of times a week.

4. ZZ Plant.
This tropical plant is a fixture in malls and offices here in the U.S., where it’s usually planted in massive quantities and blends into the background. Plant one on its own though, and you’ll really see the beauty of the ZZ’s lustrous, vivid green leaves. Overwatering the ZZ Plant is actually more dangerous than under-watering, so it’s great for occasionally negligent (but still caring!) plant owners.
