Joseph's Take
We started growing Proven Winners roses as an alternative to Knockout Roses. They are smaller meaning easier to manage as far as trimming, bloom just as much while providing more bloom color choices and are more disease resistant. They grow to be a little taller than the Drift Roses so keep that in mind when considering their placement.
