A close relative of the cranberry, lingonberries are are a low-growing evergreen shrub native to Scandinavia, Europe, Alaska, the U.S., Canadian Pacific Northwest, and northeastern Canada, but are not widely cultivated. They are often gathered in the wild in Scandanavia, to make a popular jam.
Lingonberries spread via root stolons, and grow vertically around 12" tall. Plants flower on the previous yearʼs growth in two periods - March to April and July to August. The fruit ripens in mid-August and mid-October, respectively.
Lingonberry plants require acidic soil, like blueberries and cranberries. For this reason they are suitable as a spreading groundcover interplanted with highbush blueberry bushes. We recommend planting two different varieties of lingonberry to pollinate each other, ensuring more abundant, larger fruits. The cultivars we are growing this year are:
- Erntedank: High-yielding; produces a good summer and fall crop. Moderate growth habit, plants begin to spread in the third year. Plants are 14 to 16 inches tall with dark green leaves. Berries are small to medium-size and bright red. Cultivar selected in Germany.
- Erntesegen: Vigorous plants growing to 12 inches. Most fruit forms in late September to October, ripening fully by November. Fruits are large with a high yield. Plants have good resistance to diseases.
