From the Washington Post:

What's round and red and grows at the South Pole? A tomato!

It's true. At the very bottom of the world, scientists working at the United States South Pole Station manage a greenhouse that grows fresh vegetables.

The station lies on top of the massive Antarctic ice sheet, which is up to two miles thick and thousands of miles wide. Outdoor temperatures at the South Pole can drop to 100 degrees below zero, and the sun does not shine for six months out of the year: not ideal conditions for growing vegetables.

But inside the greenhouse - known as the South Pole Food Growth Chamber - cantaloupe, peppers, cucumbers, tomatoes, herbs, leafy green vegetables such as kale and lettuce, sunflowers, other edible flowers and even watermelons flourish.
