Black thumb be damned, I love filling my home with plants. Prickly cactus, chubby-leaved succulents and sprawling ivy are my favorite types of greenery. Mainly because they are the easiest to care for, and I don’t have the best track record. In spite of my plant-murdering ways, I clearly see the benefits of houseplants. They are beautiful, they clean the air, and they can even improve your mood.
