That subject is misleading, because the answer is ALL OF THEM!
Before I started buying plants like a crazy person, I googled them all. And then pinterest started showing me so many articles about the easiest house plants to maintain, and I read those too. And now I feel pretty confident when it comes to house plants.* Outside stuff still intimidates me.
*All those articles say english ivy, and I had a couple, and they BOTH died. So I stay away from those, and call those people who say they're so easy liars!
^^I have more pothos plants than anything else. They grow so easily and I love the cascading leaves!^^
^^the snake plant is probably the easiest! I saw them down in the underground hallways of the SLC temple a few weeks ago, where they don't even get any natural sunlight!^^
I wouldn't claim to be the know-it-all plant person, but I do think the most important aspect of plant care is light. Thankfully, my house gets a lot of natural light, so the plants have been able to thrive.
Having so many plants in the house now is such a joy to me. I believe those articles that say they bring a good energy to the house, not to mention the health benefits of purifying the air. I'm fully addicted.
I just read something lovely on a home design blog that was talking about houseplants, and that when you treat them like a fashion accessory, they rarely thrive, but treat them like a friend, and you will have lifelong companions. And I finally get it. I really do look at these plants as my friends/pets, and I see them thriving, unlike before, where I have killed my fair share of plants RIP.
It sounds crazy, but it's true. I love my plants.
