greeneagle, I follow a lot of local-related searches, and can tell you that Google is doing a good job lately of getting rid of these types of spammers.
From what I can see, a site like roses nationwide, who has created local doorway pages like this usually don't last long in the SERPs. They usually get indexed and do okay for as long as a few weeks and then drop completely off the radar. I attribute this to the "newness factor" of Google. Google normally ranks completely new pages it finds fairly well at first (because new pages can't get links and
PR quickly, etc.) and then they start to drop. These new pages get some sort of "boost" by Google and then tend to be put into the pool with the rest of the pages--and since these spammy doorway pages don't get the needed links and
PR they usually end up not ranking after 2 weeks or so. The spam filters and duplicate filters usually kick in, too.
I would suspect that pages like this (keep in mind they're also spamming
for this search as well) and personally I believe that their days are numbered.
In the past few months Google has stepped up their enforcement of local doorway spam like this, and frankly I'm actually surprised that this site has been able to get away with ranking for these search terms. But, at this point, I really wouldn't worry too much about it, Google will catch up with them. I know how frustrating it can be, but give it some more time and they'll be gone.
