Ananas comosus

For home gardening, (a) remove the leafy crown (by twisting or cutting) from a commercial pineapple, (b) remove any remaining yellow fruit attached to the crown, (c) dry the crown for one or two days, (d) place the crown in a moist potting soil mix or in water until roots appear and (e) plant the crown in a container of well-draining bromeliad-type potting soil. Containers may be taken outside in summer and placed in full sun locations, but should be brought back indoors when night temperatures begin to dip below 60 degrees F.

How to make pineapple plants bloom: You can encourage pineapple plants to flower and fruit with this easy trick: Place a ripening apple or a few apple cores around the pineapple plant and cover the whole thing with a clear plastic bag for a couple weeks. The apple gives off ethylene gas that induces blooming. Keep your plant out of direct sun while it's covered to prevent it from getting too hot.
