Salix sepulcralis group Salix sepulcralis group The "Salix sepulcralis" group is a cultivar group containing all cultivars of hybrids between "Salix alba" and "Salix babylonica". The "sepulcralis" or × "sepulcralis" trees 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.. Some of the cultivars are hybrids of "S. babylonica" var. "matsudana" 'Tortuosa' and have

A very similar, closely related species, "Salix pedicellaris" (bog willow), occurs in northern North America; it is classified as a variety of swamp willow "S. myrtilloides" var. "pedicellaris" by some botanists. Salix myrtilloides Salix myrtilloides, the swamp willow, is a willow native to boglands in cool temperate to subarctic regions of northeastern Europe and northern Asia from central Norway and Poland eastwards to the Pacific Ocean coasts, with isolated populations further south in
