Have you ever seen pineapple flowers before? To satisfy your horticultural curiosity:

Most people know that pineapples grow in Hawaii, it used to be a big industry on Kauai with fields and large canneries in both Kapaa and Lawai. I have read that pineapple flowers are the reason that there are no hummingbirds in Hawaii. The colorful hummingbirds would probably thrive here but the pinapple industry doesn’t want them imported because they can pollinate the flowers, which produces unattractive little brown seeds in the fruit. Pineapples are still a major crop for the Dole and Del Monte companies on the islands of Lanai and Oahu, although Del Monte has announced they are quitting because they can grow them cheaper elsewhere.

Most people have also heard you can cut the top off a pineapple and it will grow into a new plant, so I decided to try. The first thing I didn’t know is that it takes 18-24 months to grow another pineapple. We planted some tops at the other house we rented and later moved them to our new house. They survived the move, and I’ve been planting new tops whenever we get a sweet pineapple from the farmer’s market. So we now have have a prickly pineapple patch which I keep well watered. What really surprised me is that pineapple plants produce flowers and that the flowers, in my case, are purple. I always thought the flowers were internal, that the little red leaves were the flowers.

Pineapples are the only edible plant in the showy bromeliad family, and are still very decorative. In case you want to try outside the tropics, you should be able to root a pineapple top and maybe grow it indoors behind a sunny window during the winter. When you eat a pineapple, cut off the green top at the point where it meets the fruit. Peel off the little leaves at the base to expose a 1/4 inch (.5 cm) of the stalk. It may already have some root buds. Sit the top in a small glass with enough water to submerge the exposed stalk, and place on a window sill—the one in our kitchen below isn’t even very sunny. When it has as many roots as the one on the right, plant it in good soil with plenty of compost, water it twice a week and expose it to as much sunlight and warmth as possible—for two years.
