Narrative
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 (Salix petiolaris Native Distribution from Elbert Little's "Atlas of United States Trees") covers mostly the northeastern US stretching from Maine to western North Dakota and Canada south to central Iowa. This accession would represent genetics from the south, southwestern edge of the species native range. 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. Plants of this accession, sampled in nature were multi-stemmed (e.g. avg. 20-75 ramets per genet) shrubs averaging 4.5' in height. Each genet typically encompassed a 5' x 5' area with branches very flexible at base; stems glabrous; buds brown; stems attractive, variable from red to orange to yellow, but mostly red; two stamens per staminate flower, no hairs; filaments separated (not fused); anthers with yellow pollen; flowering branchlet on staminate and pistillate catkins measuring 3 mm and hairy; ovary approximately 2 mm at receptivity, hairy; both pistillate and staminate bracts hairy, not toothed; and flowers appearing shortly before leaf emergence. Peak flowering and fall color generally occur in mid-April and early October, respectively in central Iowa.
