Of course, you can enjoy these easy-to-grow yet fascinating oddities from the plant world any time of year in your home (a few can even be grown outdoors, depending on where you live). Still, their otherworldly appearances seem especially fitting around Halloween. The blooms are sure to contribute a macabre accent to your Halloween decor. Place your batflower in bright but indirect light in a space with moderate humidity (it will appreciate a daily misting) and keep the soil evenly moist. Because air plants don’t need a pot to grow, you’ll have more flexibility when incorporating them into your Halloween decor. Just be sure to keep them in a bright place out of direct sunlight and soak them in water once a week for about a half hour to keep them hydrated.
