Air plants come in an incredible range of colours, textures and sizes. These unique plants make their home suspended in the air on a tree or areas of rocky outcrop. One of them is Tillandsia usneoides, more commonly known as Spanish moss, which is native to the Americas and drapes from trees in the Southern United States. It hangs like a living curtain and these unusual plants have no roots and get their nutrients plus water from the air which is absorbed from the atmosphere. They are typically slivery green in colours and some particular forms will even produce flowers that range from pink, purple, yellow and red. Air plants are very low in maintenance and can cope with extreme climatic conditions. Since they have no roots these plants can be used as design elements as they can be moved around easily or attached to walls. Run them under water or gently mist them – these are the perfect houseplant if you are prone to killing your indoor specimens.
