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 |

Nicollet loam soil (1 to 3% slope), slightly acid loam soil (somewhat poorly drained), Canisteo silty clay loam soil (0 to 2% slope), and moderately alkaline silty clay loam soil (poorly drained). Both wetland and upland prairie species nearby | Wild material | Plants sampled in nature averaged 2.0-4.0 feet in height. Tallest of four specimens was 5 feet in height. Progeny grown from original seed collected in nature (17 May 2019) when grown in cultivation (NCRPIS - Ames, Iowa) showed substantial variation in leaf morphology. Out of 50 seedlings, seven specimens are likely hybrids (Salix x conifera). Growth habit appears to be relatively uniform: small-medium sized plants (e.g. less than 6-8'), multi-branched, wide-spreading shrubs with near horizontal branching occurring near the base. | 1918672 | Ames 32385 |

Nicollet loam soil (1 to 3% slope), slightly acid loam soil (somewhat poorly drained), Canisteo silty clay loam soil (0 to 2% slope), and moderately alkaline silty clay loam soil (poorly drained). Both wetland and upland prairie species nearby | Wild material | Originally acquired in nature via intential sampling of Salix humilis (Ames 32385). Specimens sampled averaged 0.9 meters in height. Tallest of four specimens was 1.5 meters in height. Progeny grown from original seed collected in nature (17 May 2019) when grown in cultivation (NCRPIS - Ames, Iowa) showed substantial variation in leaf morphology. Out of 50 seedlings, seven specimens assumed to be hybrids (Salix x conifera) were selected to represent this accession. Growth habit appears to be relatively uniform: short plants (e.g. less than 6-8'), multi-branched shrubs with branching occurring near the base. Stems and petioles pubescent; adaxial and abaxial surfaces of leaves very sparsely pubescent but mid-veins relatively pubescent. Stipules present and persistent. Abaxial surfaces slightly whitish, while adaxial surfaces are slightly glossy and dark green in color. These hybrids are likely sterile; two attempts at controlled pollination failed to produce seed. | 2106732 | Ames 35549 |
