Lingonberry is an edible berry producing plant and spreading ground cover that is native to the Northern Hemisphere. This popular berry is known to be picked in the wild and used in a variety of European dishes. Berries are tart but can be cooked, sweetened and turned into lingonberry jam or syrup.

It's also used as a folk medicine with benefits similar to cranberries. Lingonberries have been commercially grown in the Pacific Northwest. This is a true cold climate plant with some varieties hardy to Zone 2 but they are limited when it comes to long, hot summers and do not do well in Zones 9 or higher.
