| 3 | Ames 36248 | Robert's Creek | Salix bebbiana Sarg. | Iowa, United States | NC7 |  | | 2024 | COLLECTED | 05/15/2024 | Robert’s Creek Preserve just north of Forest Road approximately 4.2 miles north, northeast of Elkader, T94N R5W near center of Sec. 36. | 42.91366500, -91.37990600 | 260 | Mixed hardwood forest. Very steep, moist, north-facing slope. | Wild material | Bebb's willow, Salix bebbiana, is a tight, clump forming, multi-stemmed shrub that can reach up to 25' in height that forms a rather distinct, mounded growth habit. Native to North America, the native range covers mostly Canada, but extending south into the northeastern US and also the Rocky Mountains range stretching as far south as New Mexico and Arizona (Little, E. L. Jr. 1977). In Iowa, this species seems to only be known from northeastern Iowa. Salix bebbiana can be found in a variety of habitats from pond margins/swamps to even moderately well-drained open fields. The female capsules are long (5-9 mm) with a very slender beak held on the longest stalk of any N. American Salix. This accession represents genetics from northeastern Iowa at the southern edge of its range in northeastern N. America. Specimens sampled were estimated at 30' in height. Some of the oldest, largest specimens sampled measuring approximately 8" DBH were showing signs of decline. Immature leaves are reddish or yellow green and rather rugose. | 2167645 | Ames 36248 |

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. americanum 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. | 2139681 | Ames 35919 |
