Salix brachycarpa 'Blue Fox' - Blue 
                                Fox Willow
                  
                   Unpruned, this can be a perfect plant for small gardens 
                    and tight places. It can also be used as a low hedge enclosing 
                    a formal herb garden. Prune only to shape the plant.
                  Generally found growing along mountain streams in the lower 
                    Arctic regions and south in the western half of most of the 
                    North American continent. This is a hardy plant even in exposed 
                    situations.
