I'm sure it makes little difference in taste what roses you use. This is an inaccurate statement. The roses used for flavoring are called species roses and are totally different than the hybrid teas which most people have in their gardens.
Hybrid teas have very little scent while species roses sometimes have an overwhelming scent.
Also teas usually bloom throughout the season while species roses bloom all at once and are done for the year. The Rosarium in Colorado is an excellent source for species roses. Some of their varieties date back to the Roman empire. I am not sure how old this is but it looks like it might be the syrup of roses. I've heard that you can buy rose syrup.
