Salix irrorata Andersson
(Bluestem Willow)
Family: Salicaceae
Status: Native
Synonyms:
None
Salix irrorata is a middle in size between the smaller Salix exigua and the larger Salix gooddingii of our three most common willows. Salix irrorata usually has an obvious whitish powdery bloom on its stems. It is much branched from the base. It is found in middle elevations at the side of perennial flowing water. The Salicaceae can be confused with small populations of Populus angustifolia, but willows always have only one scale covering the bud while Populus has several.
