Find the source/base of the cane with the red rose. If the source is below what is called the bud union (see the photo at the link below), then that is what we call a "sucker" from the rootstock. Go down to the base and scrape off that sucker from where it is attached to the rootstock. Dr. Huey is vigorous, and only by scraping it off at the base will help you save your white rose. Don't cut it, that won't help. If the source is above, then it is a sport. Methinks, though, that it is a Dr. Huey sucker. Here is a link that might be useful: Anatomy of a Bare Root Rose

I don't know much about roses but your rose looks a lot like a white climber for sale at Edmunds roses named Cloud 10 that I was considering buying. This is Edmunds description of it: "Spring finds this modest climber heavily flushed with pure white, full and fluffy blooms that resemble English roses. As we now expect from William Radler introductions, Cloud 10 exhibits exceptionally clean, dark green, matte foliage with a high level of disease resistance to black spot, rust and mildew making it especially good for Southern regions. Reblooms throughout the season. It is hardy to Zone 5, but there it may resemble a large shrub rather than a climber - it's beautiful either way. Flower Size: 4-5". Fragrance: Not noticeable. Hybridizer: Radler, 2013"

My first thought before reading your post was 'Prosperity'. It looks right to me. But that's no guarantee.

I "found" her at a cemetery..it wasn't in bloom at the time..but I was intrigued because of the foliage and thorn arrangement..thought it might be special. I just looked it up on HMF..and you are right..that is my rose..I am going to enjoy growing this rose! I took the cuttings 2 summers ago, and this is the first bloom I've seen..and lots of them!! Thanks...Donna
