We have grown pineapples several times from the crowns of fruit we have eaten. We have never gotten fruit even moving the potted plants in each winter to avoid our zone 7 frosts. I finally threw out my huge pineapple plant because I have small children and the leaves of the plant were dangerously sharp and cutting. There was no place to put such a monster inside. It reminded me of people that start with a cute little pet alligator and when it grows too big for the bathtub, watch out!
Hi, rroyce! Thanks for your comments. The prickly barbs on pineapple plants certainly are a consideration if you have small children. In your climate, you might try growing the pineapple outdoors in a very sunny location and building a temporary cold frame around them for the winter with a glass or plastic top. Toss in a few long strings of Christmas twinkle lights and I think the pineapple bromeliads would come through the winter without much damage. I've found the pineapple plants to be far more cold hardy than most sources indicate and they grow much better outdoors and you can build a small fence around them to prevent accidental injuries to children or pets.
