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 |

Very healthy, dark-green leaves noted in early/mid June, but leaf quality greatly declined when observed in mid-August in contrast to other populations observed in nature that seemed to maintain leaf quality throughout the season. Many plants at this site were defoliated likely due to disease (leaf spot) or tattered likely due to possible insect feeding. Specimens noted were circa 10-12 days from initiation of flowering on 12 June 2019 and during mid-August a few specimens were still observed flowering with about 10-20% of infructescences were still green. The overall phenology of this M. brevis population at this site is quite different in comparison to other populations (four) observed in 2019, with flowering being much later (e.g. 10-25 days); leaf quality lower; and synchronization of flowering extremely variable within genets of this population. | 2092646 | Ames 34610 |

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 |
