Salix serissim
Common Name: Autumn Willow
Autumn Willow is a tall shrub or small tree that can reach 3 to 10 feet in height. It is typically found in calcareous fens, wet sedge meadows, and swamps, particularly in northern and central Minnesota. It is named for its tendency to hold onto its leaves late into the fall. A species of conservation concern in some areas, it plays a key role in fen and wetland ecosystems. Autumn Willow is primarily used in specialized habitat restorations where calcareous wet conditions persist.
