Occurence in the Chicago region: non-native

Notes: Salix x sepulcralis is a willow hybrid referred to as "weeping willow." Many cultivated forms of weeping willow are derived from species and hybrids that originated in Europe and Asia. The ancestry and taxonomy is complex. For a discussion see Santamour & McArdle (1988): Cultivars of Salix babylonica and other weeping willows. J. Arboriculture 14:180-184. Salix x sepulcralis is planted as an ornamental and shade tree in parks, cemeteries, lawns, and near streams, lakes, and ponds. However, it is undesirable as a lawn tree because it often sheds its twigs and branches.

Etymology: Salix is the Latin word for willow.
