That's not the original rose. It's very likely rootstock.
Just keep digging it up until it quits coming back.

Thanks Jeri for your response! Rootstock makes sense. I just got done digging all of these suckers out as much as I could. Also poured boiling water on the spots that were at a good distance from any other plants in this area. Lets see what happens in a few months or next spring! Phew...

Try to debud the rootstock and see if you can bud it with a desirable variety you want to grow. There are a ton of videos on Youtube and several websites that tell you how. I think it maybe a better solution than to just kill some healthy roots.

Welllllll . . . " . . . Healthy roots" would realistically be roots that are not infected with Rose Mosaic Virus.

Unless Sonalia has evidence to the contrary, I'd assume this to be either virused rootstock, OR re-growth of a rose she planted, and that didn't thrive in her conditions.

The EASY way to get rid of it would be to paint the stuff with Roundup. But geeze, the stuff goes right down into the roots ... I'd avoid it unless I was truly desperate.

I dug up and moved my Falstaff and thought there was rootstock coming up in the old spot. Just yesterday the 'rootstock' bloomed, and it is Falstaff. I had to check my spreadsheet and realized that Falstaff was one of the own root Austins I got from J&P (you know that terrible company that forces you to buy roses you don't want!). So now I have two Falstaffs!!! First time I did a successful cutting:)

You may want to use a narrow tool like a drain spade or post hole digger so you can go deeper.
