Viking Weather

A little north and west of Greenland's stormy southern tip, on a steep hillside above an iceberg-clotted fjord first explored by Erik the Red more than a thousand years ago, sprout some horticultural anomalies: a trim lawn of Kentucky bluegrass, some rhubarb, and a few spruce, poplar, fir, and willow trees. They're in the town of Qaqortoq, 60° 43' north latitude, in Kenneth Høegh's backyard, about 400 miles south of the Arctic Circle.

"We had frost last night," Høegh says as we walk around his yard on a warm July morning, examining his plants while mosquitoes examine us. Qaqortoq's harbor glitters sapphire blue below us in the bright sun. A small iceberg—about the size of a city bus—has drifted within a few feet of the town's dock. Brightly painted clapboard homes, built with wood imported from Europe, freckle the nearly bare granite hills that rise like an amphitheater over the harbor.
