Sandbar Willow

  

(Salix interior)

The sandbar willow is a medium shrub native to the Northern Great Plains, Eastern, and Western North America. When water is in abundance, the shrub forms thickets on sand or gravel surfaces of riverbanks, shorelines, roadsides or ditches. It is invasive in some areas, known to aggressively spread, and overtake habitats. This should be considered with using it in landscaping.

The sandbar willow has the most narrow leaves of all willows. Serrated edges occur with wide spaces between teeth and pointed at both ends. Catkins are produced on separate plants as male or female flowers. It is very closely related to the narrowleaf willow and some consider them to be the same species.

Despite it's aggressive nature, the sandbar willow does provide various ecological benefits. This includes use as erosion control on stream banks and in restoration projects. It also has beneficial value to bumble bees and native bees. Forage for deer and shelter for game birds and other animals are provided by it's dense cover.
