The "Salix" Sepulcralis Group is a cultivar group containing all cultivars of hybrids between "Salix alba" and "Salix babylonica". The trees in this group are sometimes referred to as white weeping willow or glaucous weeping willow in reference to the mixed appearance from the parent species. It was first described by L. Simonkai in 1890 from trees growing in Romania. The group contains both weeping and nonweeping cultivars, though the best-known of its cultivars is 'Chrysocoma', the most widely grown weeping tree..
