rowan and sorb are, strictly speaking, two distinct species of tree in the genus Sorbus in the rose family; but the names tend to be used interchangeably. To compound the confusion, the sorb may also be called ‘service tree’ or ‘wild service’ in Europe, whereas in America that name is given to a more distant relation (see service-berries). All bear clusters of red or orange ‘berries’ (not true berries, but pomes), which are sour and astringent, unless exposed to the mellowing effect of frost, and most suited to making a sharp jelly which goes well with venison and other game or fowl.
