Vaccinium vitis-idaea f. majus - Lingonberry, Foxberry or Cowberry gradually forms a beautiful glossy evergreen ground cover via underground stems. Pink buds open to small white bell-shaped flowers followed by edible tart small red fruits which accounts for yet another common name: Mountain Cranberry. Enough with the common names already! When temperatures plummet the leaves turn an attractive mahogany-red. As with heaths and heathers lingonberries will benefit from an organic mulch. It is listed as a native plant of "special concern" in Connecticut; it may already be wiped-out here. And though bone hardy for us in northeastern Connecticut I have found no information as to the acceptable climate range for f. majus; I get a lot of "zone 5" but we do not know how far north or south f. majus can be grown well. Site in sun to open shade planted in evenly moist to well-drained acid soil. Lingonberry is a slow to moderate colonizer. Wide-ranging, it hales from Northern North America, Europe and Asia. Cutting grown.
