Roseberry Blanket is one of the Kordes Vigorosa roses. I have Apricot Vigorosa and Toscana Vigorosa. They would make nice groundcover roses, I'm sure, although I'm growing Toscana on a short trellis.
Here's the whole list of them:

I don't think my 2-foot groundcover rose is comparable to your Baby Blanket. It sends up canes that are 2 feet tall, not 6 feet.
I was amused but saddened by your wish: "Maybe the success of the knockout roses will encourage both gardeners and stores to try other varieties." Unfortunately, I think the opposite has happened. The Knock Out roses have been so successful that they're crowding other roses out of commerce and out of gardens.
