Plural of Bush, a spiny shrub of the family Rosaceae, very invasive and fast growth that produces the blackberries or blueberries, the most common and widespread throughout Spain. Its fruits cheered us evenings to those who have had a rural childhood. Its scientific name is rubus ulmifolius, although there are different species. The name of Bush, before sarza, seems to be previous to the Latinization of the Iberian peninsula by Rome. Bush is also the name of many municipalities in Spain, Zarza de Granadilla or Zarza de Montánchez and a surname.
