The tropical plants usually need warm climates, and even take two years to grow in the perfect environment.
So when 66-year-old Kath Paciuszko cut the top off a store-bought pineapple and planted it, she never imagined it would fruit.
Despite years going by without a sign of life, Kath, from Truro, Cornwall, never gave up on her plant.
Eventually, it grew to a whopping four inches and she sliced it up to share with her grandchildren – which she told the Daily Mail was "absolutely delicious".
She was quoted as saying: "Nothing happened for years but I kept the plant healthy and looking pretty.
"A few weeks ago, a purple flower appeared. When the flowers died off, a bulb started to swell. I thought 'crikey' but I just left it and a couple of weeks later, it started to take the shape of a pineapple.
"I said to my husband Richard that I thought there was a pineapple growing on our plant and he just laughed. But it kept growing. All I have done is water it."
Nicola Bradley, garden supervisor at nearby Lost Gardens of Heligan, said: "You need to keep them at a steady 24C or 25C. If you cut the top off and plant it, it's a bit of a fluke if you grow one.
"Very well done to Kath."
