I only have one shrub that blooms into the fall and it is my shrub rose 'Milwaukee's Calatrava'. Not sure if you like roses or not, but this one sends out a fragrance around my patio. Rated hardiness to zone 5, it has only been through two winters here in southern Indiana (one very mild) and I am hoping that it is really winter hardy, because I love it. Other than that I do not know of any fragrant fall bloomers, but would definitely like to know if there are more out there.
