Here is a closeup- I think you can also see the beginnings of a bud.

Just wondering, if your camera is a digital, it should have a micro setting to use for doing close-up shots (it's the little flower mode). May help you out in the future. If it isn't, then disregard this post...:) Karen

Did you save your lovely old rose from the backhoe? If it's flowering so well and is healthy why on earth destroy it? As the others say, it could easily be tidied up and pruned back into shape - easier to work with a robust rose that's obviously thriving in your climate with little care, than start again with something new that you may have to labour over...(Sorry, just my opinion).... Yes it looks as if it may be a rugosa or something with a bit of rugosa in it; I didn't know Hansa grew that big but others would know better. Does it smell sort of warm/clove-like? If it is H. you have yourself a very good rose that will be easy to care for in the future, once you've got it back under control. And there should be gorgeous big decorative hips in Autumn (Fall), from which you can make all sorts of wondrous old-time things like Rosehip Jelly and Tea. That's after you've finished bottling up the Rosepetal Jam, of course! :-D Seriously, you have to watch these men with their machines, they have to be spoken to very firmly, in my experience. I once had a neighbour who offered to come round to my place with his chainsaw and cut everything - trees, shrubs, everything - down to four foot high. He said it would look much neater. Honestly, they have no idea at all! (No offence to all the lovely sensitive blokes out there) LOL :-)

Immediately I thought of my yellow rose "Anthony Meilland", I think they look very similar. Am no expert on identifying roses in any way or form. It's hard for me to see if yours has the pointy petals though. The blooms on mine will blow pretty quickly, in a day or two, but it's constantly pumping out new, shiny flowers so you barely notice. I don't notice any particular scent from it.
