It would be a hybrid perpetual--most of the varieties are no longer in existence.

Here is a link that might be useful: Ameriican Rose Society History page

It could also be a China or Tea or Bourbon or Noisette or Damask Perpetual. Do you have any other information to narrow the choices?

A Burbon that fits the bill is Louise Odier. Both of my plants are 4-year old, and each has a very small fall flush (the emphasis is on the word "small") that can last into November.

Archduke Charles is another that might work. It is a China and might be only borderline hardy here, but I did recall seeing a reasonably-sized plant at the P. Rockefeller Rose Garden in the Bronx. Haven't been there this year so I don't know if it has made through this past winter alive. . Another rose that may qualify is Baronne Prevost, a Hybrid Perpetual, which I think you can find both at the Rockefeller Garden an the Cranford Rose Garden. I don't grow either and cannot tell you how big a fall flush you can expect from each.

And you might get more responses if you post on the Antique Rose Forum.
