The rose does not form any part of the insignia of the Duchy of Lancaster, but came to be seen as an emblem of the county of Lancashire, and as such was incorporated in the coats of arms of numerous Lancashire local authorities including the county council.
The traditional Lancashire flag, a red rose on a white field, was never officially registered with the Flag Institute and when this was attempted it was found that this flag had been registered by the town of Montrose, Scotland.
