Sorbus × hybrida by thrushes and waxwings, which disperse the seeds. It is a tetraploid species of hybrid origin between "S. aucuparia" (European rowan) and "S. intermedia" (Swedish whitebeam), the latter being a tetraploid triple hybrid between "S. aucuparia", "S. torminalis", and either "S. aria" or one of its close relatives. "S. intermedia" differs from "S. hybrida" in having the leaves less deeply lobed with no separate leaflets. Closely related "Sorbus meinichii" is a triploid or tetraploid species of hybrid origin between "S. hybrida" and "S. aucuparia" and differs in having the basal four to six pairs of lobes cut right to the
Sorbus aucuparia tract, fever, infections, colds, flu, rheumatism and gout. Fresh fruit are usually unpalatable, but they can be debittered and made into compote, jelly, jam, a tangy syrup, a tart chutney, or juice, as well as wine and liqueur, or used for tea or to make flour. Fruit are served as a side dish to lamb or game. Debittering can be accomplished by freezing, cooking, or drying, which degrades the parasorbic acid. The fruit are red colored in August but usually only harvested in October after the first frost by cutting the corymbs. The robust qualities of "S. aucuparia" make it
