Geoffrey Lean Doesn't Know His Greens
In 2007 - Further south, at Qassiarsuk broccoli was being harvested for the first time in Greenland,
At Umanak (70° 40' N.) is the most northern garden in the world. Broccoli and radishes grow well, turnips (but not every year), lettuce and chervil succeed sometimes, but parsley cannot be reared. Greenland - 1911 Edition of the Encyclopedia Britannica
So over a hundred years ago broccoli was being grown in Greenland, not for the first time in 2007.
