Come on over to the Rose forum & post a new thread for suggestions for your zone! We'll steer you right!
Gloire de Dijon is a Tea Noisette rated for zone 7 and above so probably wouldn't be a good choice anyways fo someone just jumping into roses.
Polka is a big tall shrub so good against a fence.
This is a site we often use to check other people's ratings and comments and check all the images.
