| 0 | PI 610668 | Aberdeen Selection | Salix pentandra L. | Michigan, United States | NC7 |  | | 1999 | COLLECTED | | Upper Midwest of U.S. | | | From naturalized stands. | Clone | Released in 1998 by the USDA Natural Resources Conservation Service Plant Materials Center, Aberdeen, ID. Selected for beauty, hardiness, appropriate growth form for windbreaks, and natural range of adaptability. During an evaluation of 15 "medium to tall tree" accessions, the Aberdeen Selection had a 95% survival. Vigor and uniformity rated above average. No observed problems with insects or diseases which affect the survival or appearance. Moderately dense stem and leaf pattern make this an excellent plant for windbreaks. Recommended for use in interior rows of multiple-row windbreaks, for landscaping, and to provide nesting and roosting habitat for birds. Tolerant of very cold weather and adapted for use in all of the Intermountain West. Soil adaptation deep or moderately deep loams, sandy loams, gravelly loams, well-drained to somewhat poorly drained soils.

Kuntze | Missouri, United States | NC7 |  | | 2025 | COLLECTED | 10/17/2025 | State Line Fen just east of the Chariton River approximately 2.75 miles west of Coatsville just south of the Missouri/Iowa border, T67N R16W SW 1/4 Sec. 22 | 40.58924000, -92.68834100 | 257 | Moist, mucky soils. Degraded fen near small creek. | Wild material | Purple Giant Hyssop is a tall (e.g. up to 6') perennial forb native to the northeastern US. Blooms extend for several weeks in the fall typically August through September and are visited by many pollinators. This accession was collected in northern Missouri and thus represents genetics from the southwestern edge of the species native range. At the collection site, most specimens had white blooms, while some showed light lavender coloration with plants averaging 4.5-5.5' in height. In Missouri, the Natural Heritage Program currently tracks this species ranked as an S1 (Critically imperiled in the state because of extreme rarity or because of some factor(s) such as very steep declines making it especially vulnerable to extirpation from the state.) and has been documented in only six Missouri counties including Adair, Atchison, Clark, Harrison, Schuyler, and Worth. | 2192996 | Ames 36705 |
