Any thumb can be green with a Tillandsia. Known as "air plants," this curious flora needs no soil to grow. As long as they receive enough light and a relatively small amount of water, Tillandsias can grow almost anywhere (not just Mars or Middle Earth, as their names connote). Native to the Americas, Tillandsias have no roots, so they can be used to accent other objects or be suspended with fishing wire to create living mobiles. If they¹re soaked overnight ahead of time, they can survive for a month in a cool spot with no water. Each varietal has a different aesthetic: Iontha Druid grows in a ball, a dense rosette of yellow-green leaves, and it blooms white flowers. A graceful hybrid, Redy turns a red hue in bright light and blooms red flowers (hence the name). Each varietal will bloom one or two times annually and they grow to be about 6–8" in diameter. Tillandsias require minimal maintenance, but be sure not to over-water them. Sitting in water for three hours every 2­–3 weeks is sufficient to keep them healthy and happy.
