The pineapple (Ananas comosus) is a tropical perennial plant that has been cultivated for its sweet, golden fruit for thousands of years. A native of Central and South America and the islands of the Caribbean, the explorers of the New World brought the pineapple to Europe, Africa, and Asia between the 16th and 18th centuries. Today, pineapple is one of the most popular and widely distributed tropical fruits in the world. Pineapple plants can be grown at home from fresh fruit purchased from a local grocery store.
Purchase a whole pineapple fruit. Whole pineapple fruits, with the crown foliage attached, can be purchased at a local grocery store or supermarket. Choose a fresh pineapple with no visible mold and dark green leaves. If leaves appear dry, or fall off easily, choose a different pineapple.
Cut off the crown top where the leaves meet the fruit. Do not leave any fruit on the crown.
Remove the bottom leaves to expose ½ to 1 inch of the stem. Five to ten of the largest leaves should be remaining on the crown.
Place the crown top in a 1/2 inch of water in a large or wide mouth drinking glass. Make sure the crown stays upright in the glass, and that the base of the leaves do not touch the water. Changing the water every 2 days will help prevent the crown from rotting.
Place the crown top in a bright area that receives little or no direct daily sunlight. New roots should form on the crown top in a few weeks.
Plant the crown top into a large pot or garden area once roots have formed. Pineapple plants prefer a well-drained, sandy loam soil that is slightly acidic. Pineapple plants should also be planted in the warmest area of the garden that receives full daily sunlight.
