Genus of 5 or 6 species of evergreen, terrestrial perennials (bromeliads) from South America. Most types of Ananas (Pineapple) produce pink flower-heads and these are followed by small aromatic but inedible fruits if the plants have been kept under warm and humid conditions. But pineapples are generally grown for their foliage - Ananas comosus is too large for the living room - the smaller and colorfull form variegatus is a better choice.
