Dormant twigs are noticeably yellowish. Leaf morphology is similar to that of S. candida and S. petiolaris. Satiny willow in nature tends to be restricted to wet habitats such as riverbanks and shorelines and its presence quickly disappates the greater the distance away from open/available surface water. This accession represents genetics from the northeastern portion of Minnesota. Satiny willow is tracked (listed Threatened in 2013) by the Minnesota Department of Natural Resources and has only been documented in three Minnesota counties in the extreme northeast corner of the state.

Native to North America, the native range covers mostly the northeastern US stretching from Maine to western North Dakota and Canada south to central Iowa (Little, E. L. Jr. 1977). Salix petiolaris typically dominates wetland areas including sedge meadows, marshes, riverbanks, and lake shores. Despite favoring wet habitats, it can also be found in dry, upland areas, especially those with high-water tables. However, longevity is generally limited in upland habitats. S. petiolaris, similar to other willow species, responds well to fire, coppicing, or heavy browsing (highly favored by deer) by sprouting new stems close to the crown. In cultivation, plants after five years will encompass a 5' x 5' area due to stems that arch from the main base of the plant. Coppicing of plants to ground level is highly recommended either annually or once every 3-5 years to maintain vigorous growth and plant health. This species requires substantial to full sun exposure and is an excellent choice for streambank stabilizations and windbreaks to reduce soil erosion and drifting snow, respectively. This accession represents genetics from northwestern Minnesota. Plants sampled in nature averaging 6-8' in height. Clump-type growth habit with minimal branching, but dense suckering (e.g. 50+ ramets per genet - typically encompassing 5' x 5' area).

Noted for it's extremely shiny, long (e.g. 7-14 cm) leaves with very elongated, acumiate leaf tips and conspicuous, enlarged glands clustered at the end of the petiole. First year branches are very glabrous and bright yellow to bright orange in color. Flowering tends to occur later in spring in comparison to other shrubby willows e.g. Salix discolor, Salix humilis, Salix petiolaris, and Salix eriocephala.

Known to occur on shorelines/dunes but also in swamps, fens, and on talus (Haines 2004) with the potential to reach six meters in height (Dorn 1995). Ornamental characteristics include glaucous lower leaf blades that appear chalky white. Staminate flowering occurs before or during leaf expansion with purple-turning-yellow anthers (Haines 2004). This accession was sampled on wet, slightly above neutral pH soils (6.0-7.3) which may result in superior performance in the urban landscape. Under cultivation, the plants grow in a widely spreading growth habit (some are nearly prostrate); however, this trait was not noticed at the time of collection from nature. Shrubs noted in nature measuring 0.5 to 2 m tall. The two areas sampled contained both Salix myricoides and Salix discolor, and likely hybrids between the two species. Attempts were made to collect only Salix myricoides based on the following characteristics: white undersides of the leaves, large stipules and finely serrated leaf margins. During collection on 6 April 2021, S. discolor was in flower while S. myricoides was not yet flowering. | 2107011 | Ames 35550 |

Suspected possible suckering via rhizomes. Very pubescent stems mostly near apical ends. This petite, shrubby willow is essentially restricted to cold bogs/fen communities and is rare in Iowa (Nekola 1990). It is easily recognized by its narrowly and extremely pubescent leaves. The undersides are extremely white in appearance resulting in a very attractive ornamental characteristic. Salix candida was considered extirpated from Iowa by Spence (1959) and Roosa and Eilers (1978). Since discovery of eastern Iowa fen communities in 1984 it has been observed extant at 26 sites (Nekola 1988) and is tracked as a species of special concern by the Iowa Department of Natural Resources Natural Areas Inventory (2021). Plants in cultivation reached heights to 4.0-4.5'.

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). This accession represents genetics from northeastern Wisconsin. Specimens sampled in nature noted as having bright red fruits with slight sweet taste. Based on fruit taste, this accession is currently (2026) being listed as V. opulus var. americanum. | 2141556 | Ames 36023 |

Species is extremely vigorous and can aggressively spread via rhizomes especially under moist, wet soil conditions. Plants averaging 50-60 cm in height with minimal to no branching. Foliage and stems are densely covered in hairs. Flowers are faint pinkish-white in color with pink-light purple spots/splotches. Peak flowering generally occurs in mid-June (central Iowa) and can extend for almost four weeks. Genetics of this accession originated from eastern-central Iowa. Species is frequently visited by a plethora of pollinators, especially bumblebees. | 2138298 | Ames 35901 |
