Pineapple (Ananas comosus) is the common name for an edible tropical plant and also its fruit. It is native to the southern part of Brazil, and Paraguay. This herbaceous perennial plant grows to 1.0 to 1.5 metres (3.3 to 4.9 ft) tall with 30 or more trough-shaped and pointed leaves 30 to 100 centimetres (1.0 to 3.3 ft) long, surrounding a thick stem. The pineapple is an example of a multiple fruit: multiple, spirally-arranged flowers along the axis each produce a fleshy fruit that becomes pressed against the fruits of adjacent flowers, forming what appears to be a single fleshy fruit. Pineapple is eaten fresh or canned and is available as a juice or in juice combinations. It's used in desserts, salads, as a compliment to meat dishes and in fruit cocktail. Pineapples are the only bromeliad fruit in widespread cultivation. It is one of the most commercially important plants which carry out CAM photosynthesis.
Older sources refer to pineapples as Ananas or Ananas fruit.
