Cryptanthus or Earth stars are unusual houseplants perfect for adding a dash of color and texture to your spaces. Small indoor plants, they're perfect for growing on bright tabletops -- and make excellent living centerpieces for special gatherings. Because they're easy to grow, earth stars are also ideal additions to your desk at work. They don't need constant nurturing, so you can enjoy their beauty without a lot of maintenance. Most earth stars have variegated foliage, which makes them striking to look at, even without flowers. Punch up the color quotient by growing your earth star in a contrasting container; a pink-variegated selection, for example, becomes a showpiece in a lime-green pot.
