Shining willow frequents wetland habitats such as swampy lakes, wet meadows and along rivers. 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. Shining willow can often be confused with Salix serissima, but the presence of glands at the base of the petiole, the colorful first year stems (most noticeable in winter) of Salix lucida can be used to separate them. The native distribution of Salix lucida is concentrated in the northeastern U.S. with scattered disjuncts as far west as North Dakota and as far south as the northern tier of counties in Illinois, Indiana, and Ohio (Little, E. L. Jr. 1977). This accession represents genetics from northeastern Wisconsin. Specimens sampled in nature measuring approximately 6' in height with bright orange-yellowish stem colors on most recent year's growth. | 2141551 | Ames 36018 |

L. Jr. 1977). Generally adapted/tolerant to wet soils this species is often found in meadows, fens, swamps, and streambanks. Attractive ornamental characteristics includes early spring, showy flowers and yellow foliage in the fall. Salix discolor provides a critical source of pollen at the beginning of the growing season for a plethora of pollinators and also serves as a larval host to many insect species. Salix discolor are commonly used in the cut flower industry for both their showy catkins and colorful, dormant winter stems. This accession represents genetics from central Wisconsin. Plants in nature measuring approximately 8-10' in height occassionally up to 25' with brown to red-brown stem colors on most recent year's growth. Some genotypes with dense pubescence on stems while others are glabrous. | 2141552 | Ames 36019 |

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 central Wisconsin. Plants noted in nature measuring up to 6' in height. Very densely suckering clumps occassionally reaching up to 10' in diameter. Stem colors on most recent year's growth varied from orange-yellow, red (predominate), to yellow. Petioles are minutely hairy. | 2141554 | Ames 36021 |

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 |
