Let me start by saying that there are no indestructible houseplants. They all can be killed but these hard to kill houseplants are just that in my opinion, hard to kill.
ZZ Plant
The ZZ Plant is at the top of my list because it is so easy to keep happy. If you kill this plant your basically a monster

Pothos
Pothos are like the cockroach of plants. They survive anything and I do mean anything. If you kill houseplants get one of these.

Monstera Deliciosa
This gorgeous plant may look complicated but I promise you it’s not! I literally neglect mine and it’s as happy as can be. If you want full care guide check out this post.

Bird of Paradise
Gorgeous and easy going the Bird of paradise is well worth the purchase if you’ve got the room because these plants get TALL.

Sansevieria
So many people kill Sansevieria but if your someone who forgets to water this plant will thrive for you. Let these babies dry all the way out before you give them a drink.
