Information quoted from the Kingdom of the West award descriptions
Membership in this Order is given automatically to Countesses in the Kingdom of the West by tradition, if not by law.
The Order of the Rose was created in the early days of the Society, before the title of Countess was used for those who had served as Queen. All Kings were, in those days, automatically made Knights, so it was felt that those who had served as Queen deserved recognition as well.
The OR is not always accompanied by a patent of arms from one kingdom to the next.
In the West, it is considered that the patent is the Countess' Royal Patent of Arms, therefore there are not two independant Patents of Arms being granted. There is no medallion or other symbol for the Order. (In some Kingdoms the OR is also a polling order, which is not the case in the West -- it is automatically granted with the title of Countess.)
