While the color most often associated with millennials is pink, perhaps green would be a better fit. While twenty-somethings have been accused of tanking any number of industries, an unexpected one they are revitalizing is flora. Indeed, one of the oldest things on planet earth is downright trendy. The Washington Post explored the millennial attraction to plants in its recent piece, "Millennials are filling their homes — and the voids in their hearts — with houseplants." Rarely can you walk through an office and not see a succulent nowadays, but the next big thing is not so big at all. Look out world, because the micro-cactus trend is the latest iteration of this obsession, and it's as cute as it sounds.

Plants have been a standard choice for home decor for a long while, but if it seems like more and more greenery has been popping up in your friends' homes (and photos), you are not imagining it. A main explanation for the growing popularity of plants is (surprise!) social media. Plant-themed Instagram accounts like Urban Jungle Blog and The Jungalow boast 500,000 and almost one million followers, respectively. It's safe to say if you've succumbed to the explosion of succulents, you are far from alone — snag some mini cacti spice up your indoor greenhouse.
