Combining two things that would never encounter each other naturally (Air Plants and Sea Urchins), results in a striking display of the beauty and diversity of nature. This is truly a unique set that will draw attention and start conversations wherever it is found. The odds are extraordinarily low that the recipient of this gift will call and say: I already have one of these. Air Plants (Tillandsia) get their common name from the fact they don't require soil. They are epiphytes, which attach to other plants or trees for support. Their roots are only used to anchor themselves and are normally removed during cultivation for aesthetics. They are not parasitic, instead they gather micro nutrients from the air and water in structures called trichomes on their leaves. As the plant dries the trichomes take on a white powder look. After watering the plant will return to a vibrant green. Air Plants must dry fully between watering because they are susceptible to rot if left wet to long. These Air Plants will only bloom once, but after the bloom they can form up to 12 "Pups", or offspring, at their base. The main plant will slowly be on its way out, but the Pups will continue to thrive and will separate when mature. Air Plants prefer filtered sunlight as their natural home is under tree canopy. This makes them perfect house plants.
