What kind of white roses bloom in late summer?

I am searching for a white rose that blooms in late summer. I am planting my garden so that I will have flowers from spring until late autumn, and I need a late-summer blooming rose to round out my garden. Any suggestions?

What kind of white roses bloom in late summer?
The brightest, pure white hybrid tea rose is called JFK. There is also a Pope John Paul II tea rose, not quite as white, and a Princess Caroline of Monaco hybrid tea, still not quite as white as the Pope John Paul II... Any hybrid tea rose will bloom all season long if you keep clipping off the dead roses, peaking at the end of the season completely covered with blooms.
