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 a source for fruit in harsh mountain climate and Maria Theresa of the Habsburg Monarchy recommended the planting of the species in 1779. An edible variety, named "Sorbus aucuparia" var. "dulcis" Kraetzl, or var. "edulis" Dieck, or var. "moravica" Dippel, was first discovered in 1810 near Ostružná in the Hrubý Jeseník mountain range of Northern Moravia and became widespread in Germany and Austria the early 20th century. Its leaves are larger and pointed, only the front part of the leaflets is serrated, and they have darker bark, larger buds and larger fruit. Similar non-bitter varieties found in Southern Russia were
