If alien life ever decides to make itself known on this planet, there is no way it will look as striking or exotic as the plants featured on this site. We know what you’re thinking: "Plants. Ho hum." But these bromeliads, platycerium and tillandsias are beautifully displayed and just as unusual as their names suggest. We recommend starting with the latter, also known as "air plants," which ironically look as if they belong on the bottom of a very deep ocean. Spindly, vibrant and indescribably lovely, these remarkable plants just seem as if they’re not of this world.
