Moist deciduous woods. | Wild material | Formerly known as Viburnum trilobum, American highbush cranberry (V. opulus var. americanum) is a North American native shrub that is utilized as an important ornamental and conservation plant that is also harvested as a minor fruit crop (jams/jellies). In nature, this variety is generally found in moist habitats typically along stream banks and swamps where ample moisture is readily available. The native range of V. opulus var. americana is concentrated in the northeastern United States and into Canada (Little, E. L. Jr. 1977). Attractive ornamental characteristics includes showy lacecap flowers in spring and bright red fruits and foliage in the fall. Fruits are tart with a hint of sweetness. The European highbush cranberry (V. opulus var. opulus) is nearly identical to American highbush cranberry other than small glands (<1 mm) on the petiole making the exact determination very challenging resulting in common misidentifications. A major difference between the American and European highbush cranberries is that the European variety produces unpalatable fruit. Recent research has shown that American and European highbush cranberries are genetically distinct and that plants of hybrid origin are uncommon (Tork et al. 2025). Vigorous early spring growth and good tolerance to late spring frosts. Genetic analysis from Tork et al. 2025 confirmed that genetics of this accession represents American highbush Cranberry (Viburnum opulus var. americanum). This accession represents genetics from northeast Iowa and thus the extreme western edge of the species native range. | 1927436 | Ames 32966 |
