ARS Rose Classification
FYI--When show schedules have a class for 1, 2, 3, etc. of "Old Garden Roses" (OGR), whatÃ¯Â¿Â½s its actually calling for are those classes that originated prior to 1867. Looking at "ARS Official List" is a bit misleading, by naming a sub-header "OLD GARDEN ROSES". Schedule writers might note, OGRÃ¯Â¿Â½s originated prior to 1867.
