| 4 | Ames 36027 | Marietta Sand Prairie | Salix petiolaris Sm. | Iowa, United States | NC7 |  | | 2023 | COLLECTED | 03/15/2023 | Marietta Sand Prairie State Preserve approximately 7.5 miles northwest of Marshalltown on east side of Knapp Avenue, T84N R19W W 1/2 Sec. 11. | 42.09951000, -93.03668800 | 299 | Remnant sand prairie in areas with likely high water table. | Wild material | Slender-leaved willow, Salix petiolaris, is a somewhat dense suckering shrub that can reach up to 10' in height with slender stems that branch minimally, but typically maintains a height of 5-8'. 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 Iowa and thus the southwestern edge of the species native range. Plants sampled in nature measuring at most 5' in height. Clump-type growth habit with minimal branching, but dense suckering (e.g. 50+ ramets per genet - typically encompassing 5' x 5' area) with winter stem colors ranging from red, orange-red, yellow, dark-green, green-brown, and yellow-green. Stems glabrous. Dormant buds occassionally black, but often reddish. | 2141651 | Ames 36027 |
