Novice gardener. I would like to know what kind of roses these are so I can learn how to maintain them. Pictures attached.

Oh, wow. Good news, bad news.
The good news is that you can go select roses that are the color and size that you really want. Maybe get a thornless one, or a heavily scented one, or something really easy care.
The bad news is, this rose you have, which appears to be a Pink Double Knock Out, certainly appears to have Rose Rosette Disease. There's plenty of info about this disease on this forum, but the bottom line is, when the disease has caused the rose to form witches' brooms (the thorny clusters you see higher up on your roses), then most likely the virus is running through all parts of the rosebush and the only cure is to dig it out, completely, making sure to get all the roots.
There is currently no cure for this disease. Where are you? It is possible the disease came with the roses when they were new, and your area doesn't have terrible RRD issues. Our area is a hotbed of RRD, and I have removed many roses, but I still grow almost 400 with no disease, so don't give up on roses entirely.
I have a hedge of Pink Double Knock Out, and 1 in the center showed symptoms of RRD. I removed that one, and the rest have been clean for the last 2 years.
So sorry to bring you bad news. We can suggest lots of new roses that you could plant! And good places to buy them, too!

I definitely agree with the RRD post by Cindi. Would also add you might wish to remove bush as quickly as possible. Since Rose Rosette disease has been there for at least a little while keep an eye on your other two bushes for rrd symptoms. The rrd shows in the center of bush in the 2nd picture. Rose Rosette is spread by the eriophyid mite. While mite can't fly it can be picked up by the wind and hitch rides on other insects. If it drops onto another rose bush that rose will also become infected. Please don't be discouraged. Thou I must admit after a 2 or 3 year battle rrd I did not add more roses for a good long time. Roses are to beautiful to resist forever. I'll just deal with rrd when it happens. Best wishes to you and your garden. After a close look at the other pictures rrd shows in all three photos. Perhaps they are all of the same bush.

Are you sure that isn't just new growth?

Healthy new growth can be red, but the extra-thorniness and tangled tips are diagnostic of the virus.

While I'm no expert on this, I have lost many rose bushes to rrd. When I first saw the middle picture. The center of bush stuck out like sore thumb. When seeing this in my yard a feeling of panic would set in. That was worth looking closely as I could at the photo. If you look at the growth of the entire bush this center has held onto it's orangey red longer than it should have. The stem the right of this center part is unusually thick. I also see leaf sets that are unevenly spaced in photo 3. In center photo you can see a change in leaf shape. They often become narrower and longer. Sometimes cupped and crinkled. How ever at the very least if I were to see growth such as this in my yard I would have cut that cane out. Since photo 3 shows narrowing of leaves and apparently uneven leaf spacing. The whole bush would be removed. It's just not worth it especially if rose can easily be replaced.

Too bad the original poster hasn't checked back in since first posting end of Oct. Hope they weren't scared away.

Me too. We are really a lot friendlier than this topic makes us sound.

I agree. Please know I responded to your post only because with rrd removing a sick rose increases the chances that your other roses will be fine. Post again if you get that urge to garden. This is a very nice place to get lots of assistance. I am new here myself.

yeah--I'm scared and those aren't even my roses--
RRD is nasty and I'm really going to be bummed out when and if it ever rears its ugly head in my area.

Meanwhile, I can hardly imagine the horror and disbelief I would feel if I posted pretty pictures of some unknown roses looking to learn how to care for them and then promptly found out that I needed to dig them out and replace them what the? that kinda thing could possibly just squish the life out of any novice gardening inklings that I might be trying to cultivate...
