Mooseberry Highbush Cranberry

Viburnum edule

Adoxaceae, Caprifoliaceae · broadleaf · native

Mooseberry (highbush cranberry, squashberry) is a straggling to erect deciduous shrub reaching 2-12 feet, native across much of northern North America from Newfoundland to Alaska and British Columbia, south through New England and the Great Lakes states to Washington and Oregon.

Mooseberry thrives in partial shade to full sun on moist, well-drained soil; it adapts readily to a range of conditions from wet to moderately dry. Once established, the plant is undemanding and requires minimal pruning. The oval red fruits that ripen in fall persist well into winter and are excellent food for birds; they are also edible for humans (though tart and best cooked).
