Two years ago my dad, a retiree in a warm continental US climate, for a lark rooted the cutoff top of a supermarket pineapple. With care it has turned into a smallish shrub that now, wonder of wonders, has what appears to be a few tiny fruiting buds on it. Knowing nothing of pineapple horticulture he hasn't done too bad in the sandy soil at the edge of a golf course. But with continued reasonable care can he expect these fruits to mature into something edible, or are edible pineapples propagated by other means? Does this plant require a pollinator or is it self fruiting? He's having fun regardless, but a real fruit would be the ultimate compliment for his efforts.
