Judi, I too have Plum Perfect. I just planted two of those in my yard (own root from Northland Rosarium--great roses!). They were little babies when they shipped in October last year and this spring I planted them in my garden. I am loving what I am seeing so far. They are blooming machines! Mine are still small (about a foot tall) and I can't wait to see what they will do when they put on a bit of age.
I have a mini rose that gets big for a mini (about 2 plus feet) called Lavender Crystal. Don't know if you wanted a mini and I don't know about a scent for it but if I recall, I think it is slight. Not sure how it would grow for you in your zone.
It is not an easy rose to find but I know Burling carries it. Since, I think you are in Washington, check with Northland and see what they recommend. They should know what would grow well for your zone.
