Air Plants

Air-plants grow on the upper branches of tall trees non-parasitically, depending on the host only for support. Most plants get water and nutrients through their roots in the ground. For an air-plant, with their roots planted in the tree tops or sometimes upon some other object, this isn't an option. But they have a solution. First, the bare roots have an extraordinary ability to soak up water like blotting paper. The slightest rain or mist, and they absorb every drop.

They also have a way of gathering nutrients. Their roots trap falling leaves which eventually rot and provide the plants with their own personal supply of compost. 20,000 different plants -orchids, bromeliads and ferns have taken up this remarkable lifestyle.
