January 10, 2014: Have you ever looked at your houseplants with love in your eyes, and genuinely thanked them for turning carbon dioxide into sweet, succulent oxygen right there in your living room? Well maybe now it’s time to do that, since it’s Houseplant Appreciation Day. They probably wouldn’t turn down a nice snack of fertilizer, either. Be warned, though — showering your plants with affection might label you as peculiar. On the plus side, it’s also Peculiar People Day, when we honor those fantastic weirdos in our lives. So shine on, you crazy diamonds!
