The Red Pearl wild European Lingonberry is very vigorous and high yielding; 1 to 1.5 pounds per plant. Red Pearl grows to 12″ to 18″ high and spreads rapidly. The sweet-acid berries are bright red and the size of a small blueberry. The plant’s oval leaves turn to a burnt red color in fall. To promote pollination for best fruit size and yield, plant with another of our Lingonberry cultivars. Hardiness Zones 3-9.
