Blooming pineapple (Ananas comosus) are terrestrial members of the bromeliad family (Bromeliaceae). You can cut the leafy top off the pineapple fruit and plant it in a pot to grow your own pineapple plant. This practice is not for the the impatient gardener, however, because it can take as long as three years for the plant to produce fruit. When the plant reaches mature size after two to 2 1/2 years, you can take steps to get the pineapple to bloom. Even with this intervention, it can take up to 14 weeks for the plant to start blooming.
