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
Salix caprea the height at which the graft is made. Plants can also be grown from greenwood cuttings, which make attractive creeping mounds. Hardwood cuttings are often difficult to root. Both tannin and salicin can be extracted from goat willow bark. The tree is not considered a good source of timber, as its wood is both brittle and known to crackle violently if burned. As with the closely related "Salix discolor" (American pussy willow), it is also often grown for cut flowers. See Pussy willow for further cultural information, which apply to both species. In Scandinavia it has been fairly common to
