Facts
Shining willow gets its name from its glossy, deep green leaves. This 12-20 foot (4-7m) tall shrub is often shaped like a pyramid, with a short trunk and narrow-topped crown. Its seeds, surrounded by a fluff that is easily carried by wind, disperse in mid-summer. Acadian hairstreaks (Satyrium acadica), among other butterflies, use this species as a host for their caterpillars. It grows well in wet or damp soils that are near-neutral in pH. However, branches are susceptible to breakage and insect damage. Many willows (Salix species) have bitter-tasting bark that contains derivatives of salicylic acid, the main compound in aspirin.
Habitat
Anthropogenic (man-made or disturbed habitats), shores of rivers or lakes, swamps, wetland margins (edges of wetlands)
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

From Flora Novae Angliae dichotomous key
16. Salix lucida Muhl. ssp. lucida N
shining willow. Salix lucida Muhl. var. angustifolia (Anderss.) Anderss.; S. lucida Muhl. var. intonsa Fern.; S. lucida Muhl. var. latifolia (Anderss.) Anderss.; S. pentandra L. var. lucida (Muhl.) Kuntze • CT, MA, ME, NH, RI, VT. Shorelines, wet ditches, swamps, wetland margins.
1×16. Salix alba × Salix lucida → Salix ×jesupii Fern. has been incorrectly called S. ×ehrhartiana by various New England authors (but that hybrid has S. alba and S. pentandra as parents and is not known to occur in New England). Salix ×jesupii is known from CT, MA, NH, VT. This hybrid is a tall shrub or small tree 4–8 m tall with abaxially glaucous leaf blades (rather than green and not glaucous in S. lucida) that show a mixture of white and red-brown hairs. The blades are mostly 2.8–4.8 times as long as wide (vs. mostly 4.2–7.3 times in S. alba). The staminate flowers have 3 or 4 stamens (rather than 2 in S. alba).
Native to North America?
Yes
Sometimes confused with
- Salix nigra:
- tall shrubs or trees 5-20 m tall, leaf blades mostly 7.5-17 mm wide, and capsules 3-5 mm tall (vs. S. lucida, which are shrubs to 6 m tall, leaf blades 11-43 mm wide, and capsules 5-7 mm tall).
- Salix pentandra:
- leaf blades 3.5–10 cm long, lacking red-brown hairs, tapering to an acuminate apex, and stipules wanting (vs. S. lucida, with leaf blades 5–17 cm long, frequently with red-brown hairs when unfolding, tapering to a long-acuminate to caudate apex on mature blades, and stipules usually present, 1–6 mm long).
