Salix fragilis 'Bullata' - Crack Willow
                              
                              Many types of Salix fragilis are enormous and 
                                invasive. However, the more shrub-like Bullata 
                                is much more compact and easier to use in a landscape. 
                                The very twiggy branches look outstanding when 
                                planted with other basket-type willows. It will 
                                make a beautiful winter hedgerow.
